CPU overheating when overclocking

[TearN8]

I got a PC for christmas last year, and just recently I felt like I should try to overclock it. I have used my PC for gaming since ive got it and have never had any issues with over heating while play games, rendering videos or anything else. I watched one of Linus's videos about overclocking (

) and I followed through with what he did and proceeded to overclock my pc. My BCLK was 100.0 and my cpu was at 4.4 ghz, I set the voltage to 1.250, restarted my pc and stress tested it. Instantly my PC overheated to 88C and wouldn't get any lower. I went back and changed everything back to normal and restarted and stressed tested it again, my pc was completely fine with 55C while at 4.0ghz. I went back and forth changing the voltage and clock speed, the best I could manage to get was 4.4ghz with 1.150 voltage at 70C but anything over 4.4 would force me to put my voltage up and and make my PC overheat again. I don't know why putting it at anything higher than that would force my CPU to overheat so drastically when my cooler should be completely fine. Was hoping someone would help, I'm pretty new to this overclocking thing and I'm not really a "pro" when it comes to PC stuff either, I'm just learning, so try to speak somewhat understandable.

Intel i7 Run High temps out of the Box

But your getting 88C with a Liquit cooler?

 

reapply new thermal paste and clean off the old stuff

[VettleBolt]

Did you use the H100i's pre applyed Thermal paste?

its pretty cheap stuff pre applyed

i clean it off and apply my own whenever i get a new cooler

Yeah I did use the stuff that was pre-applied, mind you, I still can't see how im getting that high of temps but if nothing else comes up, ill try it

[VettleBolt]

Maybe clean out your Radiator, is the Pump in the H100i Working correctly?

Is the block mounted correctly?

The Pre-applyed stuff isn't bad, but it just sits in the box and can dry out and is very thin and doesnt work as well as applying your own

I mean, when not overclocking it works completely fine even under stress testing with only 55C-60C at most so I don't feel like that's it, but I could check that aswell

[TearN8]

Is the block mounted correctly?

Yes, I am 100% sure it is, ive had it like this since Christmas and it has worked fine until i tried overclocking

Idle temps?

 

My Friend who has a Intel I7 4790k and a H105 gets 25C at Idle and a max of 39C at heavy load(Gaming)

Idle temps are around 29-35C and under load is usually 45-55C when gaming

[VettleBolt]

hmm makesure the pumps plugged into the MOBO correctly

and apply new Thermal paste

[TearN8]

Pumps are all good, will new thermal paste really do anything. When we first took the cooler out of the box we checked the paste to see if it was good and it felt fine, it wasn't tough or anything, could it really have gone bad in 6 months?

Does the pump use a USB input or fan controller input?

Is it plugged into the correct place ?

Make sure whatever controller it is plugged into is not throttling back the pump speed or not allowing it to go higher during heat up.

 

Had that problem once with a client's pc, he had a liquid cooler plugged into the fan controller but the specs clearly stated to plug the USB input to a USB on the MB and then plug the radiator fan into the other end of that setup.

No clue why but it ran like it was supposed to once it was installed correctly.

Go figure

Pump is moving at 2200 RPM

1) Wherever you have your pump plugged in ensure that in your bios that fan controller is either on full speed (not the same as turbo), manually set to 100% for all temperatures, or fan control is turned off for that fan port (which defaults to 100%). Your Corsair liquid cooler always needs the full 12 volts.

 

2) Reapply thermal paste after cleaning off the stock thermal paste. Your connection between your cooler plate and CPU may have gaps.

 

3) Ensure that your cooler plate is securely fastened to your CPU housing. Try moving it, if it's loose you need to tighten it.

 

4) A few no brainer stuff, but hey, could happen. Ensure you took off the plastic cap that came on the motherboard which separates the processor from the cooler. Ensure you took off the plastic housing the cooler plate had on it when shipped. Ensure that you have fans on your radiator blowing or pulling out of your case (fan alignment is everything.

 

5) Try testing with an open case (take off your side cover) and see what temps you get.

 

6) Try testing with a cooler room (turn AC on) and see what temps you get.

Done, same temps

Ordered some, gonna do it in a day or so when it gets here

Its as tight as it can get, no movement at all

Yup, the are sucking it the cold air outside my case and blowing it inside

 

5) Try testing with an open case (take off your side cover) and see what temps you get.

Yup, I opened the side panel and temps are still the same

 

6) Try testing with a cooler room (turn AC on) and see what temps you get.

Air conditioning was on every time and my room was cool plus I had my fan on and another fan blowing directly onto my computer (Don't actually know the temps of my room but below 75F)

[TearN8]

Even after putting on new thermal past (arctic mx-4) still no better temps

[TearN8]

Your CPU could just be a dud in the silicone oc market.  It happens.  You might just have to shoot for a lower clock speed.

Even at turbo which only brings it to 4.2 not even 4.4 it goes up to 70-75C I guess it really is a dud, or there is something so random that I could never think of that is causing the problem... so probably a dud.

[TearN8]

At least you got a great CPU...a dud one, but still a great CPU.  I don't think ya can return or RMA it though since you did push past the turbo.

I know, ah well, still has good performance, doubt overclocking would change it that much anyways, more of a bragging right
