Higher temperature or fan speed?

[TommyTwommy]

So I just got my new gtx 950, yay! It's amazing... I'm playing GTA V on 1080p ultra settings with no lags although it's being bottlenecked a lot by my Pentium E6300 and 5 gigs ddr2 ram. LOL.

 

So let's go to the topic.. I downloaded MSI Afterburner to track temperatures and control fan speeds and I've noticed that without me controling the FAN speed my gpu doesn't even try cooling itself down until it reaches like 70°C (full load ofc) ... I didn't honestly like it so I made an auto-fan speed settings that keep my gpu temperatures on 50°C, and I can say it really does affect game performance for some reason.. so my question is.. Is it better for my gpu to work on 70-80°C and low fan speed OR on 45-55°C (full load ofc) and high fan speeds... usually fan speed at those temperature is 70-85% (2800-3200RPM) which is loud like hell, but I don't really care about the noise my gpu produces. I love hearing my baby work hard!! 

 

The idle temps are 15-25°C

80 C is fine don't worry about it

Yeah I know it is.. but better temperatures = longer life-time and better performance under cost of noise

I guess so, but every GPU I've ever owned has ran at over 80 C under load, never had a dead GPU (besides this current one but w/e)

Has this been conclusively measured anywhere? Dell doesn't seem ro have any issues with their environmental cooling line of servers, and those things run HOT

high temps = less boost from GPU Boost 2.0 = lower performance

That's by design. Fans should kick in once you put some load on the card, though.

You'll get more performance out of it with OCing rather than playing with fan speeds. Besides, it would make your card run hotter and force the fans to be more present.

Lucky for you. Yesterday was 37C, though it's only 32 today..... ambient, that is.

Ok, but I don't think OCing my gpu is smart when it's already being bottlenecked by my cpu-mbo(Intel Pentium E6300 - MSI P45-Neo)

More GPU power is NEVER bad. Just crank up the AA. Use super sampling (rendering at a resolution higher than your monitors native). Increase the details (such as shadows). All of these settings don't affect CPU but can make your game look pretty.... if you have the horsepower for it. If you are being bottlenecked, then you surely have that extra compute power to spare.
