Not The Results I expected: GTX470 Cooling

post #1 of 18

Thread Starter 
I suppose I'm here because I'm curious what other people experience on their systems, hopefully as much like mine as possible.

In 2010, I built the computer in my sig. I built it because I needed more performance than my Athlon X2 64 / 8800 GTX combo, and wanted a quieter machine. I did research out the ying yang, I sold the stock fans on the FT02, bought some Scythe Gentle Typhoons, whatnot. Didn't go with watercooling because I didn't want to invest that kind of money, and the FT02 just really doesn't have the room for it. I keep the thing dust free religiously (because I own a Cat).

However: This thing is an aircraft carrier. CPU idles around 36 C, but with the fans at 65%, the GPU idles at about 53 C. That seems a bit toasty in my opinion, and if I let the fans drift much lower than 50%, I'll see about a 16 C rise in short order.

Any tips on how to reduce my Computer's Blow-Dryer impersonation? I get impression that the prime culprit in this gase is the GPU cooler, but I'm not sure if an aftermarket is worth the money at this point, or if it will provide enough salvation.

are the fins of the heatsink inside your gpu free from dust, have you taken it apart and cleaned it?

I have to say I've never even considered taking the housing off of the thing, mostly due to fear of Warranty breaking the EVGA Lim. Lifetime. At this point I've considered it to reduce the noise, but I wanted to solicit all options, yours being a very good one that I hadn't thought about.

Its very simple, just a few clips round the outside of the plastic casing, not sure if it voids your warranty.

It shouldn't void anything. You don't have to touch the screws on the back to take off the shroud.

Perhaps the GPU, haven't looked at it, but it's exceptionally uncommon for heatsinks to go "Bad." They're metal, there would have to be a considerable fabrication defect or an unlikely event happen in your computer to precipitate a heatsink going bad within the first 18 months of use. I'm using an H70 on the CPU as it is, and I check it frequently to make sure it's in good working order (which I believe it is, if I idle at 36 C )

All Scythe Typhoons on bottom are intake, H70 is in push/pull Exhaust, as Silverstone recommends for the case design.

I'll look into this, thanks Big, Methos

I'm sorry but how exactly are the Gentle Typhoons better than the 180mm AP's from Silverstone?

Unless you mean you only substituted the 120mm that's in the top of the FT02, in which case I can tell you that it's really not going to do you much difference. If anything, more exhaust going through that hole above the CPU heatsink could draw away airflow meant for the videocard.

I cannot recommend an aftermarket gpu cooler highly enough if you want a much quieter system. My 6950 had one measly fan that would ramp up to 4k rpm while playing games, it was entirely too loud. I spent $50 and about 20 minutes putting a new gpu cooler on it from arctic cooling and now I can no longer hear it over my case fans, dvd drive, or my mechanical hdd's. If you put it at 100% load it is audible but more than tolerable imo and during games it never goes above 50% fan speed which I think is around 1000-1200rpm all while keeping my gpu at 60-65*C instead of 85-90*C. Even during furmark it is quieter than my case fans! http://www.arctic.ac/en/p/cooling/vga.html

There is also a thread around here with people mounting closed loop cpu coolers on their gpu's and they run even cooler than my card but I think the installation is a little tougher unless you buy an adapter plate but it is worth checking out as well. http://www.overclock.net/t/1203528/official-nvidia-gpu-mod-club-aka-the-mod/0_30

I may be wrong but I thought EVGA allowed you to remove the stock heatsink without voiding your warranty? I'm not 100% sure and I'm sure someone else could tell you definitively. A little underhanded but you could always remount the stock cooler if you need to send it in for an rma (if you plan on doing that I would not use thermal glue but thermal pads to attach any extra heatsinks to your gpu memory).

Thanks for the thoughts - I decided I'd test the sound from where I sit -

Fans at 70%, system at 56 C (GPU), 45 C (CPU) -

Directly on top of my computer, but not touching. 80 dB

Where I sit, 2.5 feet away from computer, with wooden desk in way: 62 dB
