How I dropped my GTX 260 load temps by 25 Degrees. - UPDATE - Page 12

post #111 of 425
temps shot up to 70c over time from 64. idle temps were lower which leads me to believe that the hot air is not being exhausted properly out the back. no air is coming out of the back at all actually. maybe i can shroud the original fan to get some results.

What kind of fan are you using?

Picture?

there are two rosewill led fans. they push a fair amount of air. if i feel the side of the card that is where all the air is being pushed because that is the only part that is open now

Another idea is to strap a fan to the back of your card's PCB as well to cool the GPU itself. It can drop your temps by 5+ degrees.

Instead of bending, I'd choose to cut it to my liking, and then super glue it together (It makes REALLY strong joints). But, I would bend a inch tall strip of it around a can or something, to form a shroud for the stock fan.

With a nice, tight acrylic shroud, combined with the dual 80mm fans, it would be a cooling machine
well I'm only planning on bending the top section of the shroud and the semicircle on the back end. Pretty much it will consist of two pieces, one with both sides and wrapped around the back, the other a rectangular bit with holes cut for both fans and curved around on one end to match the other piece. then JB Weld to give it that nice strong bond. I was thinking i might make a beveled inner lining to the shroud if i can fit it to give it some extra strength and aerodynamics. I'll get some schematics up when i get access to another scanner

Alright, When I get time to take my card out again, I'll draw something up too.

I don't think so, I believe EVGA has a modder friendly warranty, which allows aftermarket heat sinks.

I can put it all back together and it will look like new.

Very cool. I remember doing this with my old Radeon 9800se. The fan was pathetic, so I took a CPU fan from an old athlon and screwed it right into the heat sink, worked like a charm.

This mod is pretty sweet as long as you don't need the slots. I wish I could do it to my SLI'd cards, but my mobo puts the PCI-e 16x's so close there is only a couple of millimeters between my cards.
