My 2nd gpu is running roughly 15 celcius hotter than the other one. It hit 99 yesterday... i was wigging out so i searched for a solution. I got msi afterburner and installed it and ramped my fans up to 100%. Knocked the 2nd gpu down to 50 and the one at 50 to about 45. I reboot after hitting the apply changes on startup. Cpu fan error , cpu overheat. I get in windows. Watch my temp and disable afterburner. I go into catalyst control center and put everything on defauly. I had turned the 2nd gpu fan in there to 100% as well. I reboot again, and noelw i cant get past bios screen due to cpu fan error, and cpu overheat warning on "ascii" style seconr bios screen (which is usually invisible). I dont know what to do. Is it fried ? Do i need a new cpu fan ? If i get a new cpu fan , will it work ?

Nah, happens to all of us. We recommend it because we've been there too. :)

800 watts should be overkill for your current configuration. All of those fans are not going to tax your power supply much.

If you OC your pair of 6870 cards to 1000 MHz, the recommended PSU is still only 700 watts, otherwise at stock, the recommended supply wattage is 600.

Edit: Before I spent the money to upgrade to a good quality 1KW or higher PSU to power a CrossFire configuration, I would consider a faster, single card GPU setup. It would require less power and have higher performance, for probably the same ballpark price as the expensive PSU.

Instead of blaming a piece of software, for something that appears to be hardware, why not open up your computer and actually verify your CPU fan is correctly installed and functioning?

About the worst I imagine Afterburner could do, and I doubt it would, is turn the CPU fan to a very low RPM or off in general. Provided no damage was done, and likely no damage was done as your CPU has thermal throttling, once your computer rebooted, BIOS would have reverted the fan back to normal.

Did you build this machine yourself? How do you know the CPU fan was installed correctly? You should verify that it's working instead of relying on software alone, especially since you're now having issues.

I built this pc myself. 2 years ago , upgrade and maintain it myself too. It was working up until the stuff in the 1st post happened. I built a frankenstein pc years ago. I know how to install pc hardware sir. I cannot get padt bios screen on last 5 attempts to even touch msi. Ill jiggle some wires though. Juat to be sure. I just "blew it out " this morning.

Well... the ground got caught in the cpu fan someways... i swear when i just looked it was clear of obstructions. Its spinning now...

Is 8000w enough to run all of this ?

Meaning 4 gpu fans (3 small on 2nd gpu , 1 large on first ?) Cpu fan , rear fan, and all other peripherals ?

Do i need a 10 or 11 to run my pc properly ?

After much trial and error after playing in bios, everything is working correctly and running cooler. Thanks for telling me to take a second look at my wires n cables. Still sont know how it managed to snake its way in there. Sorry for troubling you with my idiocy.

Typing on my phone. It sgouldve been 800w . Diablotek. See look at that /\ . ... anyways. I think i may be under powered. With 2 gpus , 4 fans and all my usbs full. Is a 1000w psu better for my rig ? Ik its not the right place to ask. Jusy wondering with all the overclocked fans.
