For about 4-5 months I've been running my set up, My gpu would idle at 40c and while gaming on BF3 my GPU would reach about 60-65c Max

Now, it's idle'ing at 45c and when I play BF3 it sits around 70-73.

Does anyone know what might have cause this increase in temperature?

My configuration has stayed the same throughout the entire time.

The graphics card is the XFX 6870.

Dust build up? Intake fans clogged with dust? Those are just a few things that comes to mind, not too sure though.

That's what I'm guessing as well.

Would you happen to know a good PSI for dusting out components?

Also, I heard you are suppose to hold the fan in place when dusting out components, true?

Yeah I usually hold my fans whenever I used those air-in-a-cans to prevent them from getting damaged. And I usually just get those "Dust Eliminator" cans from Staples :lol:

Thermal paste,dust or even the ambient.Summer usually increases the overall temps of everything in the PC.

I would suggest reapplying the thermal paste.Since you need to take the shell off the GPU anyway this is a good time to dust it as well.

It is getting hot here in Texas, but would it really increase 5c~?

Temperature of your hardware completely depends on your ambient temperature! Those are the rules and you must follow them! If your room temperature increases by 10 degrees, your hardware temperature will increase by 10 degrees.

I have one 120mm fan that came with the case, it's a bad 120mm.

Would getting another 200mm Megaflow for the top exhaust help?

It could also be a driver update that altered or reset some power management settings.

Hi guys, just new on the site. I've had the same problem as Halo Don except i just bought my cards around 2 months ago and they were around the same temps as Halo Don detailed (around 30-40 idle and 67-70 with BF3 if i'm not mistaken). My cards are two Asus HD 7870 Crossfired.

The thing is i've been playing AC Brotherhood for a while now and since isn't as demanding as BF3, my cards weren't having much problem to run it at full specs but these last few days the temp have been going up very intensely (around 40-55 idle and 75-83 ingame, specially the main card); the ambient temp hasn't changed drastically at all.

Today was the most rare cause i was playing AC Bhood and out of nothing i heared a fan noising up real fast and hard but just for a little while and then it stopped but i cheked the ASUS GPU Tweak which has a monitor and saw the temp going up for just one moment to 101 c°!!!! (in the main card, on the support card it went up like to 80ish) Then i knew something was definitely wrong.

Does any of you guys knows that could be wrong? i hope you can help me, thanks for the support! See ya!
