Hi guys , i have a problem ...
So 3 months ago i bought a second hand HD 7850 , and it was okay , overclocked well ,the temperature was always below 70 , but now i just don`t know what it`s wrong the temperature goes up to 87 sometimes , with the GPU cooler @100% , even with lower OC , i changed the Thermal paste , i cleaned the GPU from dust ....and i don`t know what else to do .... I think that my PSU is the problem , but i`m not sure , i mean i have a non-brand PSU 500W ... and the rest of my PC is ,
AMD Fx 6300
8 Gb 1866 Mhz
1 TB Seagate barracuda
and 2 fans ... and also my PC is making a disturbing noise when under load ... something like a grinding noise or something strange , it can be from my GPU or PSU ... can you guys help me please?

Grinding noise is most usually a bad fan bearing. Finding the source is a priority. Fans are easy to replace, especially if the unit in question is no longer under any warranty. Failure to replace a burned out fan can and will result in damage to the part.

Pull the side panel, load down the pc like usual to make the grinding happen, find the culprit. It's entirely possible that its an intake/exhaust fan, and your gpu is being either starved for fresh cool air, or recycling hot air that should have been removed. Or the gpu fan could have been improperly cleaned in the past, setting up a chain of bad wear on the bearing.

I did that but the noise isn`t coming from the fans , i stoped the fans with my fingers ( i know that isn`t recomanded ) and the noise was still there , and i forgot to say about this but when i move my mouse , a sound is coming from my speakers like a beeep , beeeeep , and it`s annoying ....i still think that the PSU is bad ... i`m not a specialist or something that`s why i`m asking for your help , i googled it but no answer ..

So reducing your overclock made the temperature go down? What is confusing about this? Temps below 70 are fine, I don't understand.

For only 10 Mhz , the temp reduced almost 15-20 C
