Best Fan Config for SLI Setup - Page 2

post #11 of 18
I'm a fellow Trooper owner and can give some input.

H100 on top, fans below the rad and pushing air out the top, no filter. FYI, If you want to keep the filter, remove the washers from the mounting screws above the H100 radiator.
Rear 140mm pushing air out
Front two 120mm pulling air in
Bottom two 120mm pulling air in
Side two 120mm - these fans depend on the type of gpu coolers you have. Read below:

If you have blower style coolers (hot air exits rear of case only), you might consider having both fans pulling air into the case to give the gpu fans cooler air. I currently use the EVGA GTX 670 FTW which is a blower style and it had better temps pulling in air on the side fans over pulling air out.

If you have a gpu cooler with larger fans attached and it just blows the air all over the heatsinks you should probably have the side fans pulling that air out. I used to have the Gigabyte GTX 670 Windforce and it blows the hot air out the sides of the heatsinks. I had much better temps pulling this hot air out of the case with the side fans.

I now have the windowed panel and the blower style gpu so the side fans are not an option for me anymore.

I have read that this vertical setup is the most efficient, although I have never tried it personally. From what I recall, you are supposed to rotate your CPU HSF 90 degrees so that it blows up as well. Have you done that?

He's using the H100 which is an AIO water cooling setup.

ah yes, idk how I missed that, all these fans and i never would have guess it was water cooled!

I think a blower style GPU and every other fan set to intake, except the ones on top with the radiator set to exhuast, would be the best. Gets the most air flow through the radiator (except GPU air) and creates the most positive pressure which keeps the dust out and pushes air through the GPU, so none can escape into the case

@OP

Step d) had both exhaust fans (my current setup).

Basically this is going to sound harsh, or stupid but you should try testing both cards first with 0 fans on the side panel. This will help you determine which card on top has the lesser heat dissipated. For example, I had an RMA of a 560Ti which has a stock voltage of 1.012v. When this card is placed on top, the temps hit the 80s (however it runs perfectly fine in single card), but the other card with a stock voltage of 1.000v, has a lower temperature. It could also be an issue with my heatsink (not bothered about that).

This is an image of my setup: Warning: Spoiler! (Click to show)

It might look messy, but
a) the noise doesn't annoy me
b) I love buying fans!

The white fans you see are supposed to carry the air from the top gpu, or atleast thats what I put them there for. Probably it doesn't have an impact on temperatures that much, but I saw benefits myself. What I noticed is, that near the pci slot outlet in between the two cards, there is a LOT of hot air. Now to solve this, you can either throw cold air there, or find a way to remove it. Aerodynamic experts will have a better idea, no kidding. (p.s. shroud on the top card is not removed because it was fresh from rma and I was lazy)

Thanks for the awesome replies guys. I guess my main issue is that I have 1 reference type and 1 fan type card. Getting the hot air out of the way seems like a challenge since the side fans have to be set to blow out and honestly IDK if it is more effective than to just have them blow cold air in to maybe force th e hot air out the top. Setting the top RAD fans to blow in will definitely dump all that dust into the case and I would like to avoid that as well. For now I think I'll be trying the following setup:

2 top RAD fans blow out
1 rear fan blow out
2 (or maybe 3) front fans blow in
2 side fans blowing in.
Reference card on top to get fresh air from the 2 side fans
Custom cooled card below so hot air hopefully doesn't spread to the other card.

What do u guys think? Would it be better to switch the positions of the 2 cards? Any pther suggestions?

Thanks.

Definitely have the blower card on top, everything else is good. Do you not have fans to put in the bottom of the case? I suggest putting some there to help keep positive pressure.
