So I found these fujipoly thermal pads, which seem to be amazing. They have thermal conductivity of 17 W/mK which is more than double of some of the best thermal pastes out there like MX-4 ( 8.5W/mK, which I currently use).
Has anyone used them before? And what can they be used for? Can they be used for CPUs and GPUs? I see there are sheets for "VGA" which I suppose are for the GPU VRM sections. Would they carry any benefit with them or any downsides?
I asked a few tech tubers, but everyone just ignored the question. Don't know who else to ask, so I decided to bring the discussion here.
I did a (very quick) search online, and it seems to get good reviews, although I can't seem to get much in terms of actual tests and hard numbers. (Just because it has a 15+ W/mK doesn't mean it is going to perform fantastically.)
I currently have some of Arctic's cooling pads, which work great. If/when I run out, I would gladly give those a try, just to see how they would do. Not sure if I would actually use them on a GPU core, but for something like RAM or MOSFETs, sure.
I have used it quite often with GPU waterblocks and full cover motherboard blocks, with great results. I think this is what the brand bitspower ships with, but I could be wrong.
I don't know if I have used the 17W/mK stuff though, general consensus at my time of research was that the 11W/mK was fine for my uses. Always worked great for me.
like others said , its great stuff if you are watercooling IF temperature /heat transfer is the issue. but dont think about using it on gpu or cpu. its to thick. get better paste.Waterblock or a gpu air cooler is made to fit. every component has certain,constant size.Cooler is designed with very small tolerances and is very rigid. If you decide tu put a thick thermal pad (1.5 mm or even 1mm it still creates huge heihth difference,even if you screw tightly you wont get a layer as thin as you get with paste) .so you would need then make the difference up with thicker thermal pads for the rest of gup parts, or there would be a gap between cooler and memory die. Also remember this, you think its a great heat conductor but it isnt if you compare it to cooler made of metal (10x-20 greater conductivity of heat for Al/Cu ). So you should treat it like insulator then.If its insulator then you want thinnest possible layer of it.And thats why you want the thermal paste (there are other benefits that cant be seen with naked eye,surface of cpu or cooler is not perfect,pase fills microgaps ,eliminating micropockets of air on both).I used fujipoly stuff on gpu waterblocks (vrms and memory).But i couldnt tell if they made a real difference, Gpus were the problem not vrms or overheating memory. If you feel you found best overclocking card ever and you know that vrms are the issue then get it.Also one more thing hehe . The extra heat conducted by better material has to be dissipated and removed from pc hehe.
I'm currently using Fujipoly pads on the mosfets on my Nano with a EK block. Temps improved a lot over the stock pads supplied with the block, though keep in mind that you only really need Fujipoly pads if you're doing watercooling with OCing.
The fets used on 290x/FuryX/nano love low temps, and nano only has 4 phases so I went with Fujipoly pads to drop the temps.
Keeps my 4 phases down to around 50c under full load with a heavy 1100mhz OC, pulling around 250-300w, which is a ton for such a small card. Decreased VRM temps increases ratings of the VRMs, also increases efficiency a tiny bit due to the lower resistance of all the surrounding copper traces and lower turn on resistance of the mosfets.
Pads like these are great, but overkill in most cases for most users.
Fujipoly is the best, I'd splurge and put them on any gpu's vrms and ideally the mobos vrms too. Hell I'd love extra to make a gpu transfer heat to it's backplate too. Shame it's so limited and $$$.
