Okay so I was looking to upgrade without buying a new PC, I have an i5 2500k with an ASUS P8P67 running with the stock cooler and stock settings, so the cheap no brainer upgrade was to buy a custom cooler and overclock it to hell.

I went with this cooler: http://www.overclockers.co.uk/showproduct.php?prodid=HS-061-ZA

Now I know what youre thinking, and yes I did measure up my case before hand to ensure this beast of a heatsink would fit in my case, and it would, just about. What I didnt allow for was the fact that my case fan is right above my CPU! so when I tried to put everything back together the damn case fan wouldnt let me put the side panel back on. So, I decided to try without the case fan.

My question is, will the lack of case fan make much difference? Ive switched everything back on and ran everything idle for a while, and the processor is running at around 23C, which is pretty good I think, Ive never overclocked stuff before and would like a vote of confidence before I try it.

The other issue I had installing this was a design flaw. there are four bolts you have to tighten, and if you look at the P8P67 design, theres a couple of heatsinks next to the CPU which, when the Zalman cooler is in place, makes it virtually impossible to get to one of the bolts to tighten it properly. So 3 bolts are tightened properly and one... Well.. Isnt. Id like to say it was relatively tight but to be honest I just turned it around as much as I couldwith my finger and thats all I could do. Do you think this might cause any issues?

Might have to do some tests at stock settings before trying to overclock.
 
the bolts dont have screw holes on them?
one thing you can do to see if its on tight enough is do some load testing with the case as you have it then some more with the case laying flat using the weight of the cooler, mavity being your friend and stuff

i wouldnt overly worry about it tho, too tight can be bad too if the bolts dont have springs, get clocking :)
 
You want even pressure on the CPU IHS surface. And by pressure, I mean tight but not board-cracking tight. Proof is in the pudding, fire it up and keep an eye on your core temps
 
hmmm.. Well I overclocked to 4.5ghz at a voltage of 1.32V. Im running CPUIDs hardware monitor and doing a stress test withPrime95. So far it seems stable, however the temperatures seem a little high with the core temperature average in the high 80s... Would you say this is a bit too high?

Also, I overclocked manually and intel speedstep has stopped working. its still enabled in bios but my clock is permanently at x45. Any ideas?
 
did you disable some of the power states to get the overclock?
its hard really without fotos of the bios and stuff

tweaking overclocks take time, 8pack is on this forum you could skip us novice and go straight to him :)
 
Which way around is the heat sink? are the fans blowing towards the rear of the case or up towards the top?

Does the case have no fans at all without that top fan?
 
yeh they are pretty basic overclock settings
if you want your cpu to idle lower you will need to turn the power saving states back on and see if its still stable
there's no quick way of tweaking to get the most out of it really

the good news is them volts are not harmful in any way and no games should make your cpu that hot, only benchmarks

for 24/7 running its a lot of picking a speed your happy with then slowly reducing volts bit by bit until its unstable

or 8packs way of doing it, pick a speed you want and keep increasing volts until you get it :)
