Thanks for the info. I actually reapplied thermal paste, same 65c max. The h90 pump is max speed, and exhaust fan is max speed too. Both the radiator and tubes get fairly hot which is a good thing i assume. It should mean it's making good contact and dissipating correctly.

Here's two questions,

1) My VRM heatsinks get extremely hot to touch. Is there a recommend upgrade for the Kraken fan that's facing the VRM? I have a feeling it's limiting my overclock. I have a custom PCB 980 ti which came with a separate VRM heatsink luckily.

2) Less important, but just curious. I have my H90 in a pull config as exhaust like you stated. I would like to do a push pull but do not have enough room. Would it be a bad idea to put one of the fans on the outside of the case? If I could do this, I'd be able to do a push pull config which would probably lower my temps a bit more.

Edit: I noticed my VRM's have heatsinks, however my RAM is naked. Should I get the cosmos copper heatsinks from amazon and throw them on the RAM as well, or is that worthless?

I had to slightly lower my overclock by 25 MHz core because of nvidia crashes and trying to figure out why. Adjusting memory didn't help. Couldn't run a full firestrike at the same overclocked speeds as when I had my original MSI cooler. But what's odd is temps are a lot lower with the H90. That is why I'm thinkin VRM possibly


1. They are going to get hot. As far as fan upgrades, im sure there are more powerful fans available. Perhaps see if you can direct flow from another fan to it as well. If its getting to hot it can certainly limit your OC. Need to get a temp on it somehow before you go there though IMO.

2. Sure you can pull through the case if the flow through the case top/side is good enough, I actually have all my radiator fans mouonted on the outside of my case pulling through the radiators for the GPUs and pushing for the CPU. You can buy some nice looking grills to keep it from looking ghetto if that bothers you. I think it turned out well on mine.

As for putting heatsinks on the VRAM, thats up to you. If you plan to really push the RAM overclock then they will certainly help with some stability on the highend of the OC. I have run them and not seen a significant difference, I do not do it anymore, but thats not to say thrtr isnt something to be gained putting heatsinks there. Just not a lot.

Great. I will opt in for the push/pull config then.

I need to purchase two 140mm fans now. I'm looking at the Noctua NF-A14 iPPC-3000 PWM fans, however two of those come out to a whopping $52ish. I'm trying to debate if it's worth the price. Or do you have an opinion on other 140MM fans?

Hey guys, if I get a kraken g10 for my 1080 FE and want to put heatsinks on the vrm, what needs to be covered? Is where I circled all I need or am I missing something? Not sure if I even need the ones on the right.

I don't think you need the ones on the right. I think the FETs are the ones on the left.

I know this may sound insane... I did some "poking around" yesterday and noticed the whole card was heats up. I suppose this is normal due to the GPU, VRM, etc.

Wouldn't it sound logical to toss heatsinks wherever possible to dissipate heat as much as you can? I may toss heatsinks on the Video Memory just to help out all around. Maybe it will shave a degree or two.

Does that sound nuts?
post #5556 of 6449
No, that's not nuts. That's essentially what MSI did which is why it is one of the best cooled cards on the market.

As a minimum you should have both your VRAM and VRM covered with heatsinks. Keeping both as cool as possible will improve both stability and lifespan when overclocking.

Unless you are heavily overclocking the memory, it is running well under design limitations and the heat sinks will make no difference on the VRAM. If you are overclocking the memory heavily then it can add some stability. Some find it helps a little, others not. The VRMs should always have a heatsink and a good fan blowing on the heatsink if you are using something other than a vendor designed or reference cooler.

Odd, my non-reference MSI looks almost the same, minus four RAM chips on top. Those aren't cooled.

Guess I wont waste my time buying RAM heatsinks. I just wish the U shaped heatsink around the GPU had a fan blowing on it. That heatsink gets decently hot. The NZXT Fan only blows on the ripple-shaped heatsink on the right side of card.

The midplate itself acts as a heatsink to some degree. Most of the heat from that area will be removed via the water pump/cold plate. Are you already running the G-10? You may need a copper shim if the surface on the GPU die is lower than the surface of the midplate.

Yep I'm running the G10. I actually tightened it a bit more, I suppose it wasn't tight enough. Now I max out in upper 50's instead of 65c.

I will double check if it's leveled. Does it hurt to put a shim even if it's leveled? what's the recommended size copper shim in terms of LxWxH? I see shims ranging from 15-20mm Length Width, and 0.3mm thick to over 1.3mm. I'd guess since 980 TI has a large die size, maybe the 20 x 20 x .8mm height maybe (On my MSI)

Edit I guess bigger doesnt hurt. So i would logically put thermal paste between shim and GPU, and more thermal paste between water block and shim?
