Can better cooling fix a TERRIBLE 3-phase VRM

Here is the reorganized content:

I decided to try out a new experiment with my GPU cooler because it was extremely hot and you could feel the hot air radiating off it. So let's see if that makes any difference we went from about 75 degrees Celsius to about 68 degrees Celsius I didn't do any additional overclocking but we got a bit more performance we got seventy nine point seven frames per second as an average in gta5 so it's already working which is pretty exciting now the next step is to actually add a heat sink to the vrm and I decided to go with this thing which it looks a little bit like the heat sink on an old OC said memory module I don't know if you remember them they used to make like really good RAM back in the day and I don't know what they do anymore maybe they're just turning tricks on the street or whatever but anyway it looks a little bit like that but it isn't like that it's an MDOT two nvme drive cooling thing which also has RGB on it for some reason but it's the perfect size to fit over the vrm.

I'm going to cut a bit of thermal pads so that we can actually stick this MDOT to cooler down on the vrm and then see how much of a temperature difference that makes and if that translates into better overclocking there is the thermal pad that will hopefully interface well with it. The most annoying part about thermal pads is getting the top bit of plastic off and then I'm just gonna stick it down like that there we go that actually looks like it's meant to be there you know.

I also blew a fan at it though so we were getting about 55 degrees C on the vrm which is a whole 20 degrees cooler which is pretty good as far as performance goes we were getting well we were getting eighty two point two as an average which is a pretty big jump from the 78 I mean it's not a pretty big jump but there is more performance which is pretty cool.

After this small success I decided to see if I could overclock the CPU further because we were sitting at a core clock of about three point six eight gigahertz but I couldn't get a higher core frequency going I it would just crash every single time that I booted it with anything higher than about three point six eight gigahertz I got three point seven working very briefly but then it just blue screened again so so didn't work.

Now I have to admit I'm actually really surprised by how much heat this little vrm generates I can't believe that gigabyte didn't actually put a heatsink on it now there is good thermal contact between the vrm and the actual heatsink because it gets very hot very quickly I think it's just that the little heatsink can't actually handle the vrm I think you need more cooling capacity but do bear in mind that heatsink is pretty terrible it's not an amazing cooling device but I thought it would be enough to handle the little three-phase power delivery.

I did think about adding a bigger heatsink but I don't have anything available that'll actually fit on there and yeah in all honesty I think this is just a bit of a failed experiment we got a little bit more performance but it's not going to be enough to get a significant overclock out of the CPU and besides it refuses to boot with the overclock when temperatures on the vrm are very low so even if you do like a cold start it just refuses to boot so I think there is some other stability issue going on.

So at the end of the day we got a little bit more performance but it didn't make a huge difference because unfortunately we couldn't overclock it more the max power usage of the CPU did rise a little bit but I mean it went from a hundred and eight to like a hundred and eleven watts that's definitely within the margin of error so yeah it didn't work very well but I had to know right when I had the idea I was just like I really need to see if we can push this three-phase vrm to its limit with better cooling and that got us a tiny bit more performance.

WEBVTTKind: captionsLanguage: enthis system sitting on the table here next to me like an open boil on somebody's face is that terrible old iBUYPOWER system that I've done a couple of videos on before now I really didn't want to have to do another video on this damn thing but I had an idea about how to potentially fix the bad performance on it which I can't stop thinking about so here we are now for those of you that missed the previous videos on this system basically I'm getting some pretty bad gaming performance from it because the motherboard has a really terrible three plus one phase of erm which struggles to deliver enough power to the eight core FX boo loser CPU which results in low clock speeds and bad gaming performance using this vrm with the cpu is a little bit like trying to power your Tesla with a hand crank it may technically get it running but it's definitely not going to result in the optimum Tesla driving experience and it's probably going to result in some pretty terrible wankers crap so let's see if we can help out this vrm and get some better gaming performance now I just want to preface all of this by saying I am by no means an expert on WoW anything but especially not when it comes to VR empower design now unfortunately there isn't some idiot friendly resource pointing out the limitations of this vrm so yeah I kind of had to piece together a little bit of information myself all of the documentation available is like from companies for electrical engineers to figure out whether or not they can use the componentry in their design it's my relationship with this kind of documentation is like a vampire's relationship with garlic it's there's so much math in it the only thing that I know is that under load this vrm runs at 75 degrees Celsius which is pretty hot especially considering the fact that the vrm control chip has a max rated temperature of 70 degrees Celsius and then there's this graph which actually talks about the percentage of the max rated output that is safe at a given temperature for the power mosfets in this vrm design and as you can see at 75 degrees Celsius it's only safe to use about 60% of the max that this chip can actually deal with so if you drop the temperatures maybe you should be able to get more power into the chip without the vrm blowing up at least that's my theory so let's see if it works now here are the results now with no additional cooling on the vrm so basically just the stock configuration we were getting an average frame rate in GTA 5 of 78 frames per second and we were again getting about a hundred and eight watts of power draw and a temperature of about 75 degrees Celsius now the first step is to just add a little fan over here to see if we can cool down the vrm a bit because it is extremely hot you can feel the hot air radiating off it so let's see if that makes any difference we went from about 75 degrees Celsius to about 68 degrees Celsius I didn't do any additional overclocking but we got a bit more performance we got seventy nine point seven frames per second as an average in gta5 so it's already working which is pretty exciting now the next step is to actually add a heat sink to the vrn and I decided to go with this thing which it looks a little bit like the heat sink on an old OC said memory module I don't know if you remember them they used to make like really good RAM back in the day and I don't know what they do anymore maybe they're just turning tricks on the street or whatever but anyway it looks a little bit like that but it isn't like that it's an MDOT two nvme drive cooling thing which also has RGB on it for some reason but it's the perfect size to fit over the vrm what I'm gonna do now is I'm going to cut a bit of thermal pads so
