**GlobalOffensive: Sub-Zero Cooling - A New Era in CPU Overclocking**

The globaloffensive team has been working tirelessly to push the limits of CPU overclocking, and their latest experiment with sub-zero cooling is a game-changer. With a core load that's more like five or six cores at most, the team has managed to achieve impressive results, showcasing the potential of this new technology.

Nicholas, one of the team members, ran through a series of benchmarks before sharing his findings with the group. The results are fascinating, and the data speaks for itself. It turns out that only 1.5 volts were needed to reach 5.7 gigahertz, which is a remarkable achievement considering the added power requirements from the tech used in the system. This is especially notable when considering that the team's best result came from Nicholas's later overclock at a lower voltage.

The team also ran some games to see how the sub-zero cooling system performed in different scenarios. In CS:GO, they found that their best result came from an earlier overclock, and even with cryo cooling, they were only about 10% faster than their previous result. However, in another game called "maternal," they showed that this technology is capable of delivering impressive performance even at extremely high frequencies.

The results are not without their challenges, however. The team found that the system's temps were significantly higher when using the sub-zero cooling system, which is a concern considering the cost of such coolers. With a cryo cooler expected to cost around twice as much as a regular AIO cooler, this raises questions about the long-term viability of this technology.

Despite these challenges, the team remains enthusiastic about the potential of sub-zero cooling. They've spoken with Intel, and it's clear that this is more than just a one-off project - it's a genuine effort to help mainstream users achieve the kind of overclocks they typically only see from hardcore enthusiasts. The engineers behind the cryo cooler initiative are indeed "delightfully nerdy" and consider this to be an important step towards helping users push their systems to new heights.

However, the team has one major criticism: Intel needs to do better in supporting traditional overclocking. They told the team that they would need to create tools that can help test single, dual, multi-core workloads with various AVX offsets and monitor temperatures, power use, frequency, and stability. This is a significant challenge, but it's one that the team hopes will be addressed in the future.

Overall, the results from this experiment are promising, and the team is excited to see where this technology leads them in the future. If you're an enthusiast looking for more options to push your system to new heights, these developments are definitely worth keeping an eye on.

"WEBVTTKind: captionsLanguage: en- For years, Intel hasdiscouraged the notionthat golden samples oftheir processors even exist.And yet here I am in avideo sponsored by Intel,holding nothing other than(package thuds)a golden sample,and it gets even betterbecause Intel sent over asecond, very special package,a cryogenic cooler thatthey claim can be usedto chill a chip like their golden sampleto Southern ambient temperaturesand help it reach frequencies as high as5.6 to 5.8 gigahertz in gaming workloads.And it gets even better again,because we've got a stream coming upwhere you'll get a chance towin one of these combo packs.You will find more details, links below.You know, I don't know what's up with likethis scrappy new attitudeover at Intel, but I like it.Let's go for a test drive,ladies and gentlemen,C.P.U go burn.(upbeat music)On the surface, there'snothing unusual aboutthe core I nine 10, 900 Kinside this golden foil wrapper,10 cores, 20 threads, 3.7 gigahertz base5.3 gigahertz, max boost, et cetera.But on the inside is a piece of Siliconthat was handpicked by Intel's engineersas a shining example of the absolute bestthey're 14 nanometerprocess is capable of now,these kits were actuallycreated for LTX this year,hence the packaging, R.I.PBut it's just as well,because a little more timein the kitchen has turnedinto a far more interesting experience.Let's shift our focus for a moment then towhat the heck is a cryo cooler.There are two partnersthat Intel worked withto develop these thingsCooler Master created this,a pre-filled AIO style unitwhile EK went the custom loop route.The EK solution is actually what we usedin our fastest gaming PCin the world for now video.And that's how we were gamingat 5.4 gigahertz with all course.So let's start with anunboxing of this puppy.First things first, you'vegot a triple radiatorso far nothing, especiallycryo looking about thatthree, 120 millimeter fans.It's all pretty normal.We've got a actually whatlooks like a pretty beefy pump,especially for an AIO.Like it's nothing for like a custom loop,but that looks fairly considerable.Alright that's a kind ofnon-standard connection on there.And then, ah, Whoa.Now this is where the magic happensinside the CPU block is acustom Thermo electric coolingor tech module that drawsabout 200 Watts of powerusing an eight pin PCIexpress power connectorfor the uninitiated techcooling takes place.When an electric currentpasses through a thermal couplecausing heat to be absorbed on one sideand then to be output on the other side,the more powerful the Peltier,the more cooling you get,but also the more heatyou have to deal with.Hence the need for a triple radiator.Now on a normal CPU, only AIO cooler,like the Coursera one that I'mpulling out of this system.A triple rad is kind ofoverkill on the cryo cooler.It's pretty much a necessityas we're going to see.And there are some other considerations,you've probably noticed that even thoughthe cooler master masterliquid ML three 60 Sub-Zerohas a separate pump,the CPU block unit is too largeto account for just addinga Thermo electric cooling module in there.That's because there is ashroud to prevent humid airfrom contacting the cold surface here.There's a freaking humidity sensorto help manage condensation.Yes, my friends andthere's a power controland monitoring boardthat communicates withIntel's cryo cooler software.It's not the greatestmountain for the pump,but I did manage to kind ofscrew it into the top of a fan.It's more intended forlike a slit like this,or an empty 120 millimeter fan Mount,where you could just put thethumb screws through the Mount,into the threaded bracket,but hey, it's on there youall wanna go Sub-Zero with me,we've already applied the bios updatethat we're gonna needfor the crowd cooler.So all that's left is tothrow on our XMP profileand fire up windows in order to avoidany potential for bottlenecks.This system's loaded up with5,100 megahertz Ram from crucialas well as an RTX 30, 90,that's actually on it's own completelyseparate water cooling loop.So Intel told me to expect hymnsas low as minus 10 degreesCelsius in unregulated mode,but recommended sticking with cryo modefor daily driver operation, cryo mode usesCPU telemetry data to avoidunnecessary power drawand tells the cryo coolerif something's improperlymounted or something.Intel did mention thatonly 10th and 11th genand onward CPU's are designedto provide that feedback.Although technically youcould use the cryo coolerwith anything you wanted,as long as you made thenecessary modificationsto the condensation trout Yolo.Now let's talk about another thingIntel has been cooking up calledOSI thermal velocity boost,regular thermal velocityboost already existed.And it's just a higherlevel of turbo frequencythat your CPU can gear up intowhen it's running cool enough.It's the OSI part that's new.So get this, in a highly unusual move.Is that competition I smellIntel is adding thisfeature to existing Siliconwith a microcode update,allowing users to adjustthe factory thresholdsfor thermal velocity boostusing their XTU overclocking utility.Alright, so why don't wehave a look at the software,first of all, there's the cryo software,which is very simple.Okay so there's standby,cryo and unregulated.I mean, should we just fool aroundwith unregulated mode firstand see what kind of temps we see?Oh, we're down to 16, 43 degree.What does it doing 10 degrees?What's going on here Intel?It's definitely working.These wires right here thatgo from the top of the unitwhere the power goes indown to presumablywhere the tech is, yeah.Down at the base, these are warmand our CPU temps are lookingpretty interesting as well.Check this out.We've already dropped downto zero degrees Celsius.Now it's not letting mego below zero degrees,which is interesting,I would guess because ofthe climate that we're inand the local humidity.Yeah, Do. 9.8 and the cooleris actually at minus 10.Now let's pull out the old thermal cameraand have a quick looky boo here,you can see the warm cable.Everything up here is prettycool, pretty normal lookingradiators, not super toasty.Oh, interesting we can see thehot side of our tech modulethrough this grill here.And then we can actually seehow chilly things are rightaround the CPU socket.That's actually one of the bigger concernswith running an unregulated mode.Not necessarily that you're gonna getcondensation on the cooler itself.Cause you got that little shroud on itto keep warm air away from it.But rather that the board itselfmight have air going across it.That is going to cause condensation.So we can see this even moreclearly around the back.That is freaking Chilliewell below ambient Tims.Now let's have a look at the interface.Nicholas already ran some before numbers,both with the CPU running at stock speedsas well as with his ownsort of conservative attemptat using thermal velocityboost over clocking.But Intel sent me over what they calla starting point recipefor our golden chipthat they're hoping will give us5.6 or maybe even 5.8 gigahertz in games.It's not the mostuser-friendly thing ever.56 multiplier, dang that feels crazyto even put in four core 56.So then 55 and then 54.So they want 5.4 gigahertzall core 5.64 core.Huh? Well, we applied it, Oh yeah.I need voltage things.Oh, I need one pointfour five volts adaptive.Terribly short max power should be dead.Paul.My understanding is thisis a very new feature.Woopsie daisies.Well, that's what you get for notchanging all your voltagesettings and stuffbefore overclocking to 5.6 gigahertz.Good luck everybody apply.Is it running faster?Yes, it is definitely.I saw it boost past5.3 for a second there.Idol temps look good.Right in that 12, 13 degree range.Oh, five degrees belowambient temperature right now.Alright thank you forthe coil line RTX 30, 90.We love you.Oops, whoops, bloody hell orone round in let's tab out.And what are we seeing here?5.4 max, okay.Do we want to try a more extreme recipe?- Might as well.Okay everything else here is the same.We're just going for 5.7 on loads up to,you know what, no forgetit 5.8 up to two cores,5.7 up to four CF you know, golden sample.One of 200 can do itstart with 1.475 volts.Okay, let's do four eight, five.Yeah. We definitely have chorusthat are seeing 5.5 gigahertz.I'm pretty sure this is more performancewe're seeing anywhere fromthree seventy to three eighty,I'm even touching 390FPS from time to time,it might just be working,highest clock speed scene 5.5gigahertz throughout that run.But every core touched it.Whoa hey, now that we're out of game,we just saw 5.7 gigahertzon three of the cores.What that tells us then isthat Counter-Strike globaloffensive is more likea five to six core load,at least with whatever we've got rightrunning in the background,which frankly isn't much otherthan our monitoring tools.So what I'm gonna do now then,given that that is stableis Nicholas is gonna run us throughall the benchmarks that he ran before.And we'll get you that comparativedata, the results are in.And this is fascinating guys.We ended up needing about 1.5volts to reach 5.7 gigahertz.And this is a real lessonin optimizing your overclockbecause more voltagemeans of course more heatand especially combined withthe extra 200 Watts from our tech.That's a lot for even atriple radiator to manage.So in CS:GO for example,we actually got our best resultfrom Nicholas's later overclock at a lower voltage.You can see that his99th percentile frames.So that's the slowest 1% of framesthat the system is outputting.We're actually about 10%faster with cryo cooling,but not pushed to the limit.Do maternal on the other hand,shows us exactly what thiskind of cooling is capable ofin a best case scenario,going from a stock CPUon a triple water cooler,all the way to 5.7 gigahertz,we went from 184 to 222 FPS.Even if it did ultimately end up runningabout 20 degrees hotterthan the conservativemore lightly over voltage attemptas for shadow of the tomb Raider,it didn't end up being particularlyCPU limited in general.So this shows us areally good mix of gamesthat will either benefit alittle bit in certain situations,benefit a ton or potentiallynot benefit at all.Of course, a few more FPSin lightly threaded loads like games.Isn't going to mean much ifthe whole thing falls apart,when you fire up a workload that exceedsthe 230 ish watt limitof the cryo cooler block.So does it fall part?Over the course of an extended test?We found that while our system performancewas on par with a regular triple AIO,our temps were significantly higher,which is a bit of a downer consideringthat a cryo cooler is expectedto cost about twice as muchas a regular AIO cooler.With that said not everybodyruns extended all core loads,and it should be noted that this is a veryfirst-generation attempt, fromtalking to Intel about it.The cryo cooler initiativeis actually less of arandom one-off project by ahandful of nerdy engineersthan I expected.Although it should be noted.The engineers were undoubtedlydelightfully nerdy,and they consider it tobe more of a first steptowards helping mainstream usersachieve the kind of offthe wall frequenciesthat they normally only seefrom hardcore over Clockers.Now, the timing of Intel's interestin squeezing extraperformance out of theirnear redlined flagship CPUis definitely a little susas the kids say, but for my part,I'm not one to look agift horse in the mouth.And in my opinion, theenthusiastic communityshould support initiatives like thisin hopes that we see more of them.On the subject of support.That was one area that I told Intel.I would like to see them do better.The reason traditionaloverclocking, you know,where you just set an all core ratioand increase the CPU voltageis still so popular isbecause it's simple.This kind of overclockingwhere you're settingindividual core frequenciesunder various loads.And that various temperature thresholdswith various offsets is not simple.And one of the biggestchallenges is validationwith a normal Alcor over clock.It's easy to tell if the system is stable,you just run a stress test overnightand see if it errors out.But if Intel wanted this to getto the point where let's saya Puget systems or origin PC is gonna shipa pre over clocked, cryogaming PC to a customer,they need to create thetools that will help testsingle, dual, multi-core workloads withand without AVX offsets,et cetera and simultaneously monitordye temps, power use,frequency and stability.That way everyone from a systemintegrator to an end usercan know with confidencethat if they get a bluescreen down the road,it's because of a driverupdate or something.And not because their CPUflew too close to the sun.So bottom line, I am enthusedto see more dials forenthusiasts to play withand very excited to see where the roadmapfor coolers based on this tech leads uspun definitely intended.If you enjoyed this video,maybe check out one ofour previous attemptsat Sub-Zero cooling I'll tell you guysthis is significantlymore elegant and quieter\n"
