**Temperature Testing with the Arctic Accelerator II**

Temps are significantly better yielding a more impressive result overall stepping up to 1500 rpm now we get a similar picture. The Excel or 3 is roughly 1 degree warmer than the Morpheus - but the PCB components are much more effectively cold and at 1850 rpm the accelerator provides the best vrm and memory cooling in the stack by a decent margin with the peak vrm temperature reading at just 56 degrees C.

**Impressive Temperature Results**

All right so temperatures are really impressive on an open test bench but what about inside the end case M1 well I first tried to cram the accelerator II in with the pre-installed fans but no matter what I did I couldn't get it to fit. I even tried unmounting my CPU cooler and repositioning all of the custom power supply cables but the main conflict here is with the front IO connectors honestly I probably could have wrestled it in there but I didn't want to risk flexing the PCB any more than I already was and possibly damaging the 1080 Ti because that would be a very expensive mistake.

**Configuring the Accelerator II**

Instead I decided to try and stall the accelerator 3 without the pre-installed fans as this is a configuration that I see quite a lot for the N case M1 and finally I was able to fit it. And I was very interested to see how the temperature would differ now with 120-millimeter fans running underneath also I was able to slide the EK backplate over the top as I was using a different mounting bracket so hiding that bare PCB is always appreciated.

**Initial Temperature Results Without Fans**

To start with I had the bottom 120 millimeter fans configured as in since this is how they were configured with the EVGA sc2 core but the temperatures here were very underwhelming. I started with the fan rpm set to 2,000 rpm and even here we can see both the GPU and vrm temps are way hotter than they should be but it's the memory temps that were the main concern here even with the fan rpm lowered to 1500 which I would consider to be a fairly reasonable level for these fans the gddr5 X memory was peaking at 90 degrees C and the GPU clock is all over the place.

**Improving Temperature Results with Bottom Fans**

So I wanted to see how the temps would differ with those bottom fans now in a pull configuration. And the airflow design here would be a re-in take from the CPU cooler and then exhausting down the bottom. Before I clicked run on the test I was blown away literally by the amount of airflow that was being pushed out of the bottom of the case seriously it felt like there was a fan wanted directly at me.

**Fan Configuration Boosts Temperature Results**

It turns out that flipping the fans is all it took to get the GPU vrm and memory call again at 2,000 rpm. The Excel or o3 is surpassing my expectations with a peak temperature of 50.3 degrees C and even at 1500 rpm which was virtually silent with headphones on we're just below 60 degrees C for the GPU and the vrm in memory are still relatively cool.

**Noise Testing**

If you want truly silent performance the Excel or three at 1000 rpm is still performing very well at just 71.9 degrees C but 1500 rpm is ultimately what I would recommend. For a quick noise test I didn't get the chance to test the accelerator 3 with the pre-installed fans since it was quite noisy outside during the day.

**Conclusion**

But at the end of the day with the accelerator 3 in my system I did get a quick chance for some recording and I was impressed yet again. So you probably get the idea where I'm going with this the Arctic accelerator II is going to be replacing the EVGA SC to stock cooler in my personal build in the end KSM one for pretty obvious reasons not only is the cooling performance outstanding but I really enjoy the industrial look with exposed fin stacks and copper heat pipes.

**End Case Comparison**

The clean unbranded look is something that I envision for the end case I'm one build when I first set out to build it and to finally achieve that is a pretty good feeling even when compared out of the box to the Morpheus from Rajan Tech it makes a pretty solid case with vrm and memory temps which we'll call it across all fan profiles and GPU temps which were within a single degree.

**Call to Action**

So as always I want to hear what you guys think in the comments section down below let me know what you think of the Arctic Exelero 3 and also if you would like to see this compared to something like the NZXT G12 or the EVGA hybrid which are both liquid cooling solutions.

"WEBVTTKind: captionsLanguage: enCPU cooler swaps have been growing in popularity a lot on this channel and you guys seem to really enjoy the Morpheus to cool swap that we looked at a couple weeks ago since then though there have been so many requests for this particular cool that we're gonna look at today and that's the Arctic accelerator 3 so just like the Morpheus - this is an aftermarket cooling solution for your GPU which aims to do a much better job than what's typical the EVGA SC 2 core that we'll be comparing it to today is what I'd consider the middle ground for a GTX 10 atti cooler it's significantly better than a founders Edition or blower style card but being a 2 slot card it is a few degrees behind bigger options like these tricks or gaming X cards now compared to the Morpheus - from Rajan Tech there are a couple benefits here also the first and most obvious is that the accelerator II actually comes with fans whereas with the Morpheus - you'll need to purchased and install your own now that might not sound like a big deal but it does increase the cost of the final product by about $30 and when you factor in the fan splitters that you'll need as well you're looking at about $100 for a functional cooler the Excel or oh 3 though can be had for $69 on Amazon and comes with everything you need some people will prefer the Morpheus - though in terms of flexibility and as I mentioned in the initial review I actually enjoy the fact that users are able to mount their own fans and basically customize the cooler to look like or perform however they want whether it's high performance static pressure fans or quiet knock towards with the accelerator 3 though there's no mounting your own fans unless you want to use zip ties or if you happen to have fans sitting directly underneath something that we'll be looking at a little bit later in terms of the way the cooler looks I'd have to say it looks pretty dated when standing next to a modern cooler and shroud design like the EVGA SC 2 there's no real gamer aesthetic or design happening here and if you came here looking for RGB well prepare to be disappointed the accelerator is all business when it comes to calling but it would be nice to see a refresh of this dated shroud design I'm not asking for lighting effects or anything like that but something other than this black glossy plastic would be real nice let me know what you guys think down below anyway the fans that come print sold our 92 millimeter fans that spin up to 2,000 rpm and Arctic claimed that these are pretty quiet as well and I'm going to have to say that I definitely agree size also might be a concern for some users as when we looked at the Morpheus - despite the very impressive cooling performance you do end up with about a three and a half slot card which unfortunately meant that it couldn't fit in my personal system inside the NK m1 the accelerator however does manage to squeeze in there with a few conditions which we'll go into a little bit more depth later the compatibility list from Arctic site is pretty extensive also which is nice to see pretty much any moderate to high end and video card is compatible with the majority of AMD cards supported as well and despite the RX Vega 400 or 500 series not officially being supported I have seen people use the accelerator 3 with a few of those cards here and there so I wouldn't be too quick to count them out and lastly the spec that matters most the accelerate cooling capacity of 300 watts which is 20% less than the Morpheus - which is rated for 360 watts this gives us a pretty good insight as to what the results could be but as always there's only one way to be sure so time to prep that 1080 TI for installation and see what this thing is all about okay so the 1080 Ti is prepped and ready to go and of course all of the mounting hardware comes included in the box along with some aluminium heat sinks which we'll be using for the MOSFETs and memory I did try and use these stock EVGA SC to cooling plate like I did with the Morpheus too but unfortunately the cold plate for the excel or three is quite large and ends up conflicting with these screw positions for the original cooling plate as I said though I did try it and although idle temperatures looked pretty impressive the cooler was evidently not making anywhere near enough contact with the GPU if we take a look at the EVGA SC 2 cold plate we can see where the cutouts have been made for it to fit with the original PCB cooling plate whereas expectedly the accelerator 3 doesn't accommodate it so we will be using the aluminium heat sinks with the included thermal adhesive so starting with the gddr5 X memory chips apply a thin layer of thermal adhesive mount the heatsink with some downward pressure and then repeat for the remaining chips you'll also want to do the same for the capacitors and then the MOSFETs that are part of the vcore vrm but leave the inductors which are these silver square components here as those are fairly heat to learn let the adhesive dry for about two hours and we should be ready to mount the cooler now the first thing that we need to do is Mount the spaces on the cooler itself and this is done with these adhesive rings now in the case of the 1080 Ti I used the small spaces that were included just keep in mind that if you're using an AMD card for example you may need to use something different so with the cooler ready for mounting we need to apply the foam pad on the flip side of the GPU so the mounting bracket doesn't create any shorts and then we can mount the GPU to the caller with the mounting bracket spaces and screws plug in the fan header and we're ready to go so with the excel or three on the open test bench we performed all three tests as usual 1000 rpm for our silent profile 1500 rpm for the moderate profile and usually we'd be testing 2,000 rpm for the performance profile however the max rpm that I was able to achieve for the accelerator 3 was 1850 rpm not sure why this was happening though since in total these fans would be consuming under 400 milliamps of current which is far below what the fan controller is capable of anyway let's get to the results so on the graph here we have the EVGA SC to Morpheus 2 and the excel or oh three all at be three different fan speeds and let's start off with the accelerator 3 at a measly 1000 rpm here the GPU temps are significantly better than anything that the EVGA sc2 has to offer however the lack of airflow means that vrm and memory temperatures are a little bit warmer compared to the Morpheus to at 1000 rpm we're not too far behind and in fact GPU temps are within 1 degree C and the vrm and memory temps are significantly better yielding a more impressive result overall stepping up to 1500 rpm now we get a similar picture the excel or 3 is roughly 1 degree warmer than the Morpheus -
