Yeah, stulid gave me a link for a guide to OC an i5 to 5.0GHz. I've only been adjusting the multiplier so far since I know messing with the voltage can possibly break the board. I'm going to have a good read of that guide.
Speaking of the i5, I've read online in the past hour that it's an average that most can get 4.4GHz since some people who are unlucky can only get 4.2GHz while others are really in luck and get 5.0GHz depending on the CPU itself.
4.0GHz seems stable so far through all the test's I've put it through, and I've updated the drivers for the GPU and CPU besides the ones mentioned before. I'm sure I'll get more from it, but I'm going to try and play some more games on it now to see if anything happens.
As for fans, I only have the stock ones currently installed. The one is at the front of the case (I think this is intake) and has a blue light behind it, there's another at the back for exhaust I believe. The CPU cooler is positioned so that it pulls air from the front intake fan which passes the graphics card out the exhaust fan at the back.
Do you think those temps I was getting was normal? I tried another test in OCCT but used a small data set instead which is supposed to generate more heat for the CPU but only got exactly 1°C per core extra on load.
Also, how do I make the system stay on my multiplier all the time? stulid mentioned it and I believe I disabled the right option in the BIOS but it's still slowing down to 16x...
