So, I just upgraded my 4 years old C2D 8400 setup to a i5 4670K one, and finally my Asus GTX 570 DirectCUII can work like it is supposed to instead of the CPU being a bottleneck. I have just reinstalled my windows, I have the newest drivers from nVidia, and it does it regardless of OC's or if I have Afterburner on or not. So, at idle, the fan is 930RPM @ 40C, and then pretty linearly climbs to 1600RPM @ 74C under load. But when it hits 70C (with a few seconds grace period) , it instantly jumps to a deafening 3300RPM and will stay at it until it is down to a stable 69C, going just as suddenly back down to the linear curve. To add insult to injury, at full load, the 3300RPM manages to cool it down so it fluctuates between 69C and 70C, so it never stops screaming unless the GPU load drops a little. Is this something I can fix, is it 'working as intended', or should I take it back to the shop ? It is over a year old, but does have a 36 month warranty, so... Here is a picture showing it happening, and it does it in games as well, it isn't just furmark. Notice how the fan speed % doesn't change, it just jumps to 3300RPM no matter what fan curve or setting it is supposed to be.
Nope, didn't work. But at least now I know, grace period is around 10 seconds. Temperature limit... 70C...
Is it actually going faster, or MSI AfterBurner just reporting this? If it actually going faster, then look for a a graphic card firmware update (also refereed as: vBIOS), on ASUS website. Just be sure that you don't install UEFI/GOP ready firmware for your graphic, else you'll be screwed if you do. If that doesn'thelp, then I am afraid that you may need to RMA it.
It sounds like a leaf blower when it does it, so yeah. I tracked the RPM/% of the default mode and plotted it to afterburner. This is how the default temperature curve my card uses looks like: Quite useless, eh ? My current motherboard is the GIGABYTE Z87X-D3H, so I think it has UEFI ? Anyway, the update I found just says "Your graphic card of current system don't mach this VBIOS." and quits.
That temperature curve is epic lol Odd you did not come across this in your old system but I would guess you may have been CPU limited where as now you are GPU limited. Add more points in the curve on afterburner or find the vga bios update for your exact card. Hmm if afterburner is not stopping it from maxing out at 3300rpm then its vga bios or a fault on the cards fan resistor.
Yeah, I was CPU limited for sure, GPU usage almost never got over 75% and temps were maximum of 65C. But I can't add points, that is just a plot what it looks like _IF_ it was a curve in afterburner. No matter what I do, after it hits 70C, it will go to 100% fan and ignores all curves and settings. It even seems that dropping to 68C doesn't do anything, so if it kicks in, the only way to stop it is to quit anything GPU intensive. I couldn't find an update that would work, are there some other places as well ? GPU-Z says my bios version is "70.10.55.00.01 (P1263-0000)" But this is a problem with my card, and not some designed thing, right ? Maybe there is some thermal protection that is somehow set way too low, I don't know. I guess I'll see if the warranty covers this...
It is not a rare problem. I have a 7870 that has a faulty fan resistor, does exactly the same as yours you cannot control it with software, 55 degrees and it has two 4000prm fans. I just swapped the cooler. had a quick google around and cant find a known issue like that for your card however.
Yea your card is faulty. RMA your card, if its under warranty, else replace the heatsink/fan of the graphic card. :/
