Crossfire heat solutions.

post #1 of 7
Thread Starter 
So I'm thinking about picking up another 6870. Ideally id get another twin frozr 2 because of its twin fans. My issue is with the potential heat of these two cards.

I have a HAF 932 case and I could remove the side 200mm and replace it with 4 120mm fans, but I'm a bit of a noob when it comes to airflow dynamics, will this help my crossfire temps? Would the extra intake wear out the exhaust fans out? Are there any better cooling solutions than this (water is out of the question)? What would be the best fans to get?

I just want Ultra settings on BF3. Thanks OCN

Well, the card at top PCIe slot will be warmer. But I think it won't be too hot.
Twin Frozr Cooling should be doing fine with Barts GPU.
May I you your current GPU temp at full load?

Front fans = intake
Side fan = intake
Top fans = exhaust
Rear fan = exhaust

replacing the side fan size should not matter, as long as you have one there.

Should not have a problem as long as thats your setup in my opinion

Does your mobo allow for a space in between if you use 2 cards? I relocated my sound card which lowered GPU temps. Do you have one that is in the way of air flow?

PCI slots on GA X58 UD3R from top to bottom are
PCI Slot 1 - PCIe x1
PCI Slot 2 - PCIe x1
PCI Slot 3 - PCIe x16
PCI Slot 4 - PCIe x8
PCI Slot 5 - PCIe x16
PCI Slot 6 - PCI
PCI Slot 7 - PCIe x8

to get full PCIe x16 bandwidth, you need to place the card at PCIe x16 slot (slot 3 & 5) but it only separated by one PCIe x8 slot (slot 4).
So, no space for 2 slots card like Radeon HD 6870 if you wanna get full bandwidth.

PCIE ports 1 and 3 are 16x and ports 2 and 4 are 8x. I'm not sure if a CF connector would reach between 2 and 4 though.

I'm not using any PCI cards right now so the only heat generating parts are...well...the heat generating parts.

I have my 460's in sli and I haven't changed the stock fan configuration from HAF 932. No issues with heat yet. Really the only way to find out is to get the new card and push it. If you think it's too hot then I guess you can get more fans there, but as long as you continue to push cool air in from the side fan, your cards dual fan setup should keep the temps at bay.

They do make extra long CF connector's for situations where video cards are spaced out a bit more than usual. I saw a bunch on ebay.
