How I dropped my GTX 260 load temps by 25 Degrees. - UPDATE - Page 11

post #101 of 425
Very nice idea. I was going to go to Microcenter and get some cheap fans to give it a shot, until I realized I have a PCI sound card right between the two of mine

depending on the size of the card and the placement. you might be able to do what i thought up on previous post

lol i love this site. makes me feel good that there are people crazier than me. anyways.. mine is a 260 that i have in my girlfriends computer. the before temps when oced to 734core 1512shader and 1152mem are 63c max load.. never did a furmark on it.. lets see if this thing performs better than the accelero i have on my gtx 285. maybe wasted 70 dollars on looks.

I designed an alternative mount and shroud that would hopefully give a little more direction to the airflow from the 80mm. Basically ill give a little lift t the side of the 80mm closest to the outside of the case so that the air goes more in that direction. I can do both 8mm's on the bottom GTX 260, but the top one will need this specialized mod.


as an alternative to this variaton I'm designing a low profile setup using 40-60mm fans for those people who use dedicated audio cards. I'll get a schematic up soon.

I wanted to do something like that. What would it's net look like?

OK, my scale is a little off onthis, but if i can find my spares i think i can get this together. Either use 8x 40mm fans in a grid across the heatsink or 6x 60mm fans in a grid. This will allow just enough room for most PCI audio cards to have a spot.

I was planning on using some acrylic i have laying about and bend it into the proper shape, and then glue the other bits in with JB weld or something similar, then have some hex mesh across the hole for the fan if there was enough room. The acrylic id be using has enough thickness that i could probably drill and mount some nuts for the screws into it.

That would be awesome!

I want to implement the existing stock fan to blow the hot air out.

If you have any spare acrylic that you wouldn't mind tossing my way, that would be killer.

Its the cheapest thing in the world, but i actually have like 5 sheets of it that i used for a previous mod. You know how to bend it to your will? Also, the placement of that 40mm fan on that other schematic isnt really practical unless you get a 40x10mm and have it sit competely vertical. in that case though it would just get in the way of the stock fan's airflow. Better just to use the 40's or 60's in the grid on top.

I don't know where to get around me

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
