Planning to install an air fan to help circulate things around the GTX 460

post #1 of 23
Thread Starter 
I had a thread going in the NVidia Cooling forum about my GTX 460 running hot when playing games.

It seems to average at about 80-84C on BFBC2 (sometimes hitting 95C on parts like very smokey things like exploded tanks and helos).

I bought the Acer Aspire Predator G7750.

And I noticed, to sort of aid their unique, quite cool-looking case design, they have missed out on one thing, a side case fan. They have the huge fan on the back which also serves as a radiator for the CPU Water cooler (all stock).

However in this picture of the removed side panel:

You can see that there is no fan on the panel, now I am planning to install a fan, not sure of the size -- please advice on the bottom vent (which is the top one in the picture), would this aid in cooling, and as there are no places for screws, would using some kind of adhesive work?

Also I am currently looking at the Sharkoon Silent Eagle 2000 120mm fan, would this help circulate things?

Any additional air flow over the cards will help. My folding rig (2x GTX460's) has a 120mm fan hanging on a couple of strings just for some air. The vent looks kinda small but even a 80mm would help.

Great biggrin.gif, I'll take a look on Amazon for 80mm fans, I plan to use some double sided carpet tape cut to size.

Any recommendations on what fan to go for? And will I need to hook it up to the fan controller or is a simple hook-up and always 100%-speed deal.

I have a 120mm fan blowing air from the sidepanel right onto my 460.

Card hits ~ 60C in BFBC2 and ~68 in Furmark

With all case fans on low and gfx goes from 50 to 60%

I am looking at that.

Yeah the side panel that I plan to use (the bottom one-top one in the pic - as bottom one in pic does not go through all the way xD) is right next to the GTX 460, also I am planning to get a GTX 580 or 590 soon.

Yeah, I need to get some circulation. Here's some temps I measured with EVGA Precision OSD.

Idle : 39 - 45C
MegaVideo : 49-53C
Osu! (V-Sync ON [60FPS]) : 55-57C
Osu! (FPS Limiter Off [958FPS]) : 71-73C
Battlefield Bad Company 2 : 80-84C Average (90C + when looking at stuff like smoking cars and stuff) [This is okay -- and the Card-Fan isn't running at full whack]
Just Cause 2 : 88-91C Average [Iffy Side... Card Fan running at 90%]
Bulletstorm : 95-101C Average [Unacceptable]

If you are worried about sound levels you may want to try and fit a 120 in there cause generally they'll be quieter for the same air flow. If not just about anything should work. As far as fan controllers go its again just up to you if you can put up with the noise all the time.

Why dont you look at installing a 80mm fan on your gtx 460? Its really simple, all you do is remove the plastic mould on the graphics card, then grab 4 cable ties, and set the fan to intake air, and attach it to the gpu. There are copper pipes on some gtx 460/65s, depending on your brand yours should have some too.

Even if it doesnt have the copper pipes, you can attach the fans using other small crevices on the boards design. It doesnt void the warranty AFAIK, because all you need to do is remove the fan and reattach the plastic cover. When i did this on my GTX 465, my temps went from mid 80s to mid 60s max. So i lost like 20C temps for cost of like $10...

PM me if you would like more info on how to do this.

For some reason, I actually like loud fan noise xD and it means the fan is doing its job all the time.

I'm looking at Sharkoon Silent Eagle 2000 RPM, whether to go for 80mm or 120mm I'm not sure. Probably 80mm because 120mm might just be ineffective with the size of air-vent.
