So I built my computer around 6 months ago, since then I've installed a new 1TB Hard drive, a new 700watt PSU and a GTX 670.
The CPU fan has always been really loud but now its just getting down right annoying, anyone know what I can do?
I already have three fans in the case and they're reasonably loud as it is, but that doesn't bother me so much.
If it is not your fan controller turning your fan faster.
You can try servicing your fan, by opening it up, look for a little sticker and then rubber panel that covers the ball bearing and then putting 1 drop of oil/lubricant on it (not wd-40. Sewing oil, gun oil, motor oil, silicone spray). This is not available on all fans.
but best way is just get a new cooler.
The 212+ or evo is very quiet. and costs $20 or $30 respectively.
I seem to be talking to myself here, anyway I bought a 212 should be here tomorrow
Yeah that will help the temps and the fan is much quieter than the 80mm/92mm (can't recall the size cus I havent used one in a while) stock fan. Also the 212 will allow you to put a sizeable overclock on the CPU without overheating.
The BIOS probably has the fan speed set to max. Go in and manually set the speed to a lower setting. I recently built my wife a computer and the ASRock BIOS had the fan set to full 100% speed all the time. I went in and set it for a lower minimum speed and it slowed it down to a nice quiet level. What settings you have will depend on what motherboard and what BIOS you have but you still should be able to get into it and change the CPU fan controller settings.
