Gtx 480 SLI placement - Page 2

post #11 of 15
Good work!

I have a suggestion:-
With this present arrangement (Zotac in the upper and Spitfire in the lower), Zotac gets 70-71C and Spitfire gets 64-65C. This is very good. I wonder if this can be further 'improved'.

What I have in mind is to 'equalize' the load temp difference between the 2 cards, ie bringing their load temperature numbers closer.

At current setup, Spitfire receives cold ambient air and so it benefits much. But its exhaust runs against the exhaust of the Zotac. See pic 1.

So, if the Spitfire fan is reversed from intake to exhaust, the Zotac might breathe out easier (at the expense of the Spitfire, or course). See pic 2.

At the end, both the Zotac and the Spitfire might end up having 67-68C as load temp.
It might be worthwhile to conduct this experiment.

BTW, is the side panel just a wire mesh as shown in the pic in the OP?

Yea it's just a wire mesh. That's a good idea about the exhaust. I'll give the fan flip a try and report back.

Ended up having GPU1 now load at around 68c and GPU2 now at 65-66c. Also added a fan for the intake for both:

Previous:
Zotac 70-71C / Spitfire 64-65C

Now:
Zotac 68C / Spitfire 65-66C:applaud:
(1 degree of Spitfire trades off for 2-3 degrees for Zotac)

This looks good. I think that additional intake fan does contribute by pushing air into the gap between the 2 card (pic below).

Actually the zotac dropped to 65-66 and the spitfire rose to 68ish. However the zotac hit 73-74 earlier so this is a def improvement.
