Should I delid my i7-6700K?

[hotcoolfool11]

Hi everyone, 

 

I've been having alot of overheating on my i7 6700k. it hits 99 degrees on max load.

Let me explain this better: My CPU idles at about 25-35. But for example I used Prime95 for this test, It would instantly jump to 80 and then in a few seconds hit 99.

What could it be?

 

I have a H115i Liquid Cooler and LOTS of airflow. I also use CoolerMaster MasterGel Pro which has a Thermal Conductivity of >8 W/m-K. I have also made sure that it is well spread.  My liquid cooled 1080 doesn't go above 60 degrees on full load and its overclocked. Motherboard: MSI Z170 Gaming M5.

 

Can anybody explain what is happening here?

I mean, if you delid it the temps would obviously drop, but it's still weird that it's getting so hot with your AIO and with your airflow. 

 

It is unlocked so I assume it's overclocked, have you tried to remove the overclock and checking what happens? Maybe the CPU has worn a bit so the volts could be overheating it.

well one dont test with prime 95 its a power virus and its totally inaccurate for testing an overclock or really anything at all ,use something like cinebench 3x back to back or aida 64

its much more realistic workloads that still generate more stress than a game or something like that as its a render program

you should also check to make sure your pump is still working, and remount your cooler or just check to see if its mounted correctly

If its overheating to that point, it is probably an issue within the pc, and something that deliding wont solve

probably not true, i had an i5 4440 runing in a small case that waas overheating it and after i delidded it it stopped running at 100C and auto shutting down, now it runs at 80c with aida 64 and the only thing i changed was the TIM between the IHS and the DIE

Well it's just boosting to 4.2. I can remember I could overclock it to 4.6 and it wouldn't go over 70 degrees, that was about 6 months ago.

I want to delid my CPU, but dont want to buy the delid gadget. Also can i use my CoolerMaster Mastergel Pro on my CPU?

Is the 6700k stock, without multi-core enhancement? If so, those temps are way too high for that size cooler even running Prime95. I'd strongly suspect the cooling as I know you can do better than that with a Hyper 212. Recheck the mount, make sure the pump is running. Feel it when it is running, is the body of the radiator the same temperature on both inlet and outlet ports? If there is a big difference, you might have had enough fluid loss for it to stop working well.

Hey man! Well in my iCUE software it tells me that the pump is running at 3200 RPM. Would that be trustworthy to tell that the pump is running? Or how should I check it?

It's possible to hear the pump. It might even have a very-very slight buzz/vibration when touching.

Ok, let's take it the pump is running, but let's also check if there is enough liquid. Put your hand on the block, the tubing, and where it enters/exits the radiator? Is it all about the same temperature, or is there an obvious difference? If there is enough fluid you shouldn't notice any temperature change. If there has been liquid loss, half will be noticeably hotter. This could also depend on mounting orientation.

When I hold my hand on my 1080's liquid pipes. I can clearly feel it vibrating. But on my H115i almost nothing.

I mean he should try and figure out what is causing the overheating before going straight to deliding 

[jones177]

The i7 6700k is the hottest chip I have ever owned. At stock it ran 10 to 15c hotter than my i7 8086k with 5ghz on all cores. 

 

For silly hot use an i7 6700k with ASUS multicore enhancement. 

 

If your keeping it delid it. Better still, upgrade.

your AIO could be dying how old is it? might be time to look into a new cooler
