i5 2500k OC high temps

Have you checked all your fans are the right direction, sucking in at the front and blowing out the back. And that is WAY too much thermal paste, you only need half a small pea size.

I actually used about the same on mine, came out a bit to quick. But my temps are fine. Not sure the "exact" rule about paste applies to every chip/setup tbh. But yeah normally I would not use that much at all.

Dear ******

Sir that isn't overheating, mine reaches 85 degrees at stock.

Guess I'll have to ring them. I'm going to feel awfully geeky sitting at my desk talking about cpu temps....
 
Hang on,

Your CPU fan is connected to the CPU fan header on motherboard and not a system fan header?

I may be pointing out the obvious here, apologies...just trying to make sure everything is ok befote spending money on RMA postage.

Also, your CPU fan is rated at 1500rpm, have you disabled CPU fan throttle in bios?

You don't have any resistors on the CPU fan header cable do you?
 
Just had a look at your cpu pic zoomed in. It looks more like a cream cake.
You only need a bit of tim approx the same size as this ( - ).
Check that the bracket is mounted correctly and when you mount the cooler tighten each screw 1 full turn then do the other one until tight. Fire up and check temps.
 
This may be obvious, but, you have checked that the CPU fan actually spins haven't you?
I only ask as this wouldn't be the first time I've encountered a fan splitter cable that didn't actually work!
I think I have 1 of the Akasa PWM splitter cables where it seems that one fan is always on 100%. I've had other splitter cables were none of the fans work.
Maybe yours is somewhere in-between those 2 extremes?

Well, ok smack in-between stuck on full speed and not working at all would probably be working perfectly, but you know what I mean...

The CPU fan is indirectly connected to the 4 pin connecter through a PWM Fan Splitter Cable

Yeah I know I went over the top. I've tried setting it with less but it makes no noticeable difference. I cant mount is again im out of paste, but I did try 4 times.

It runs from ~750 rpm idle to 1500 rpm flat out
 
How old is the CPU heatsink? Is it full of dust between the fins?

Thing is; even with your 'generous' amount of paste there is a good thin spread on the photo after you removed so I think you are right by saying with less paste you won't see much difference between temps.

I don't know much about your cooler....Have you seen any reviews to compare your temps to? Maybe its just a baa-baa cooler.?
 
Its brand new.

I dont think its the best cooler of overclocking tbh, However I thought it would be fine for ~4.5GHz.

Just ordered the upgrade kit of my old Noctua NH-U12P. Gonna see if that does the trick.
 
Very , Very odd.

As have no experience of the motherboard it may be that my next comments are way off :o (would not be the first time and probably not the last ...)but:-
1. Have you 'set' the PWM correctly in the Bios?
2. Wether you have or have not set it correctly - can you try without PWM - let it run full whack and see what temps you get. (Fault somewhere in PWM?)

Good Luck.

The Gelid is a great cooler i've fitted a couple onto friends builds and it's been more than capable of keeping clocked Ks frosty.

Personally, if the fan is operating properly and you've tried smaller amounts of TIM, then it's probably a contact issue between the HS and the CPU.

It may be that the bracket, for whatever reason, isn't creating enough pressure bewteen the 2 surfaces so that heat transference isn't as efficient as it should be.

I would contact Gelid - they will probably send you out new fixings gratis if you link them to this thread or even send you out a replacement unit - as your results indicate a problem rather than a poor pruduct.
 
If it was a heatsink or contact issue surely his idle temps would be effected too?

That suggests to me either a warm case with bad air flow or the fan on the heat sink isn't spinning fast enough?

Not necessarily, there may be sufficient contact to keep idle temps within normal parameters but when it’s under full load there’s just not enough heat transference to deal with the extra load.

It's not uncommon - search the general HW forum for heat/temp issues. It may not be his problem however - but it's certainly a possibilty...

It could be – but from his posts he seems to have eliminated those.

Ok thanks,

I am going to try to contact Gelid directly.

I have tried everything I can think of. I have taken the cooler completely off and refitted it from scratch doing everything up as tight as I could, not that it was loose originally.

Idle the temps seem fine ~30°C, it's under load I get the problems.
 
I have the exact same cooler on the exact same cpu running 4.5 24/7 and get nowhere near you high temp side...

I know this may sound stupid and may have been asked before but when you mounted the fan onto the cpu you did have the arrow pointing towards the back of your case ? (looking again at the pics looks like you have the fan the correct way round...:))

Also the fan at the back of your rig, does it blow air out or in ?
