Hmm... interesting, i will definately look into this, thanks for the info. Glad to hear that you got your temps down by so much. I should have some washers somewhere, so i'll try that later on and get back to you with the results.
Ok OP I was having similar heat problems with my Corsair H60 and I resolved two problems with it today:
1. I had to put washers onto the backplate between it and the motherboard to help apply more pressure between the CPU and the waterblock.
2. There was a small capacitor near my socket that was preventing the H60 from making good contact with the CPU.
Now that I have done that my temps have dropped 20C under load.
Have a look at yours and see if this can help you. If there is indeed a capacitor interfering, try rotating the waterblock by 90 degrees.
I put the washers underneath the rubber ones that came with it because AFAIK they are conductive and I didn't want them touching my motherboard.

Hi Guys!
I have both good news and bad...
First lets get the bad news out of the way:
I was going to do what was suggested and place some washers to increase pressure on the CPU... but while i was at it, i thought i would remove the CPU just incase it was something as simple at the temps reporting wrong, so i undid the lever and released it. It was then i noticed something - the metal cap/heatspreader (whatever you call it) was not centered, so i touch it and it moved - instantly i knew, the guy who i bought it from had already delidded it... and obviously hadnt done a very good job.
Thats the bad news...
Now for some good news:
With the CPU already delidded i decided i would have a go at fixing it, i should point out that i am no computer technician (although the guy i got the PC from claimed he was...). So i removed the metal cap thingy )) and wiped everything clean using 70% achohol wipes. The guy who delidded it didnt remove all the black adhesive so i very carefuly scraped it off using a plastic card. So with everything now clean and smooth i put the CPU back into the motherboard and put a short line (didnt want to put it the full length as i knew it would spread) in the middle of the die (i think that's what it's called) and then carefuly put the heatspreader on top making sure it was centered before finaly clamping it down with the motherboard clamp. I then put the waterblock of the H100i back on, making sure everything was tight... Then i put the PC back together and tested with crossed fingers, hoping i hadnt screwed it up even more - luckily i hadn't.
Instantly i could see a difference in temps at idle, which were sitting at well... ambient, or maybe just a degree over. So far so good - nothing has started smoking I then started up Prime with crossed fingers, temps instantly hit 35c and then rose to about 40-41 after a couple of seconds and stayed there... great!!! I left it running about 5 mins (normaly by this point, temps would have hit 100C within almost no time at all), came back, checked the temps and the CPU went no higher than 51C... wow - HUGE difference:biggrin:
So turns out that all my bad temps were the result of a botched delidding.
I am sure if i got better thermal paste to apply (like one of the liquid metal ones), that i would get even better temps - but for now, i will stick with using Thermalright Chill Factor III.
I would just like to personaly thank everyone here for trying to help me with the issue i was having - it is greatly appreciated, and also great to know that there are people like you who are here if anyone needs help.:thumbsup:
Thanks again everyone:thumbsup:
Nobody would have guessed that, sure glad you found the problem! Cool story!
Guess now you can crank her up and see what she's got
Wow, OP, working on a delidded CPU took some real courage given that you didn't have much experience with building PCs. Congrats!
Those temps are actually incredibly low, seems like you're getting some benefit from the delidding.
Thanks, i didnt feel comfortable doing that at all, was actualy mildly shaking, cause i was worried incase i damaged anything.
Yeah, good temps - but you have to bare in mind that i am running at stock for the moment - and slightly undervolted too so.... yeh. But still, im glad i found the issue and was able to fix it
Too bad you didn't take pictures.
I've read that depending on what thermal compound you use it can suffer from pump out over time.
At least the original owner did the hard part for you. Wonder why he didn't just take the xtra few minutes and clean it up completely.
If the heat spreader was not oriented exactly upon the black adhesive that was not properly removed, the result might be that the lid would end up riding higher than it was in the first place, due to the unevenness of the cut/breakline.
Yes, i had considered that, which was why i scraped it off... but whatever was causing the high temps, it seems to have been fixed now, thankfully.
The gap between the silicone and heatspreader is/was the biggest issue as far as temps go. There is a really good thread by Idontcare which shows this. It looks to be the thermal bonding agents hit or miss even application that caused the heatspreader to be uneven at times. When the original owner failed to clean off all the adhesive he pretty much didn't accomplish anything at all. He might have had worse results afterwards. Maybe he figured it was just a dog of a chip. Time will tell but looking at your current results you'll most likely get to a reasonable overclock with reasonable temps.
I currently have a 4690k/Gigabyte z97mx-gaming 5 combo topped off with a H100i housed in a Arc Mini.
I decided to work on my overclock profiles this AM.
Using the latest Prime95 to stress and Aida64's monitoring software. Prime seems fine at such a low overclock. Was more curious about the temps it would generate under long term loads.
4ghz at 1.09v's
Temps after 2 3/4hrs. Temps should be close to stabilized but the average is slowly dropping as time goes on.
Max 71,71,71,69
Ave 65.9,67.1,66.2,66.1
Judging by the temps I don't think my 4690K would benefit much from doing a delid job....Probably not enough compared to the hassle/risk involved at least. The loaded core temps makes me think so as there looks to be very little variance between them.
You fixed it!
Ok, ive been running Prime at 4Ghz, and although i set the voltage to 1.09v, it seems the BIOS decided it didnt like that and bumped it up to 1.104V (at least thats what HWMonitor reports it as), so now for the temps:
Max CPU temp at the above clock and voltage was 60C
Max Core temp was 61C
So pretty good i think.
Super
Thats also some pretty wierd situation you had.

Your results look impressive now. You still had HT enabled or did you disable it to get a more realistic temp comparison.
Don't worry about bumping your own thread....It's not the for sale sub forum.
No, HT is/was enabled when i got those temps - im not gonna cheat, haha
All normal CPU settings are/were enabled in the bios, including HT and Turbo. Only thing i left disabled was Multicore Enhancement as that auto overclocked the voltage cores too high, although it also gave me better idle temps when enabled...
Well as long as bumping the thread isn't against the rules then thats ok.
