I've got a 0DB GPU that by default shuts off the fan below 60C. It's an EVGA 960 SC, and I have ordered the GTX 1060 SC with pretty much the same cooling design/heatsink. However, when I first got it, I was afraid of seeing 45-48C temps at idle, so I set a custom fan profile using MSI AB. The fan was set to 20% (750RPM) and the temps were a nice and cool 35C at idle now. But then, it's been about 2.5 months since I got it, and when I check the fans of the GPU there's quite a bit of dust. I haven't been gaming much though, and the PC is generally on for about half the day at least, sometimes up to 18 hours. I then had a suspicion that this dust buildup could have been exacerbated by the fact the fan stays running all the time, even if it is at a low speed. To make matters worse, the fan blades are incredibly tiny (compared to my GTX 750 SC before that) and it seems difficult to get the dust off the back of each blade. So I've got two questions basically: 1) Is there any appreciable long-term penalty if my GPU (a GTX 960/1060 SC) idles at round 45-48C with the fan turned off? 2) Does spinning the fan at a low RPM when idle exacerbate dust buildup in the GPU's fans? Could this buildup be slowed down by turning off the fans at idle? Put simply, if you were in my shoes, what would you do? Spin the fans at 750RPM/20% and get 35C idle temps, or have the fans stop spinning at idle but get higher idle temps of 45-50C? Thanks! PS: Noise is not an issue. I do not hear the fans at all at 750RPM.

1) No, there isn't. People run at much higher temperatures for extended periods of time (if not 24/7), yes? 2) To an extent, yes. It is drawing air in as opposed to what would just settle on it anyway. Compressed air is cheap and effective if used correctly. I use a lint free cloth and wipe off flat surfaces regularly as well (to include fans). Takes 10 minutes once a month even when you are OCD like I am. Personal opinions will vary widely, but I like to keep things as cool as possible in my case. Ambient temperature from the card will slightly affect everything else in there. I always adjust my fan curves to run 100% of the time my system is on and ramp them for the higher temperature.

The only reason fans don't spin until 60C is to eliminate the noise and even then the fans at low speed don't make much noise anyways. When comes to dust...it will get collected on your GPU and everything else regardless, all you have to do every so often blow it off and will be nice again, you can't prevent dust from entering your PC. I have STH10 and I've used DemciFlex filters for a while ( year or 2) and I was very anal about my PC being dust free, yet dust would find its way in, its unpreventable. I took front intake filter off and I see big improvement in my case temperature and dust accumulation!!! it's not much more than I had with filter tbh. and I have quite a bit dust i my area. Your idle temperature is normal as you don't run fans so it's obvious, but if that was me I would rather keep my system as cool as possible, it will prolong longevity not only of your card but your system

I agree. I leave my GPU fans running at 12% up to 30C and have them ramp up from there. My personal preference is keep things cooler and just do a little extra cleaning once a month or so...

I've been monitoring the effect of this on the temps of other components in my PC. - HDD temps are unaffected, the same before and after - CPU temps are also seemingly unaffected, but it may be 1-2C higher after, but it's marginal at best - Chipset temperature is the one that is affected, since it lies totally underneath the GPU and it's only source of airflow is from the GPU. With the GPU fan on, it idled at around 46-47C, but with the fan off it idles at 50-51C. I'm not sure if this is something drastic that I should be worried about or not. - "Airflow" temp may be 1-2C higher than before Not sure what other temperatures ought to be monitored. Some advice based on the above info would be appreciated.

Your temps are fine, although I would prefer to keep my chipset slightly cooler but nothing to be worry about, even having it watercooled it dons not make much difference, but check you PCH temperature, it shouldn't be higher than 50-60 at the most.

Really? If by PCH you refer to the chipset temps, then well it is 45 at the MINIMUM with the GPU fans turned on at idle. When under max load, the chipset temps are 65C. I was told it was nothing to be worried about...

He's talking about your motherboard ambient temps, I'm sure.

No its nothing to worry about, but if your M/B ever is unstable that might be cool-print, my PH is at 29-30 max but its watercooled, you are fine.
I'm also anal person and normal temps for others might be to high for me

Buy some dust filters for your case, run positive pressure - problem solved with needing to clean

To be clear, when you say "blow", do you mean blow air with your mouth, or something else?

Temps are fine, but dust is the enemy of electronics, keep your case clean.
I really wouldn't worry about idling temps, now load temperature above 80c, that would start to make me a bit nervous.
Honestly if you're that worried buy the extended warranty and you can sleep easy.
