I7-7700k temps

Recommended Posts

Posted · Original PosterOP

I have an I7-7700k that I've had for awhile now. It works great! it meets my demands, but I'm always looking for ways to improve my PC and get just a little more FPS out of my hardware. I've noticed that when looking online I find temps on it to be a lot lower than mine. I've seen on one forum that someone has idle temps of around 27-30C. I don't have anywhere near that! My idle temp after running continuously is anywhere to around 44-50C. I might be wrong, maybe it's supposed to run this hot, but i don't think it is. When gaming I stick to around 80-87C on BF5 (max/high), but i find quite often that it spikes momentarily up to 90-100C. I've tried stress testing the CPU and comparing it to others temps, using Aida64, stressing the FPU, I INSTANTLY hit 100C and have massive throttles(Highest 57%). I've seen other forums using other software and I've compared it to them aswell, and i find that others temps are always better than mine. for example, on Intels community forum I found someone using CPU-Z for over an hour and only getting temps of 80C (that is unheard of to me, any high intensity stress test maximizes my thermals). I understand that Kaby Lake processors run hotter than the original, but I'm not so sure mine should be running this hot, and I cannot pinpoint what is wrong. Recently, I delidded my CPU and put in Thermal Grizzly Kyronaught but I do not believe it improved my situation as much, if at all.  

 

Lowest Idle temp:40C

Max Idle temp:54C

average stress temp:100C

Gaming temp AVG:85C

Idle temps around 44-50c with a H115i look a bit hot, and those load temps are significantly hotter than they should be.

 

I'd suggest re-applying thermal paste both under and on the IHS. Those temps are significantly higher than my (non-delidded) i7 8700K even when I'm pushing it to 5.1GHz, and may cause damage to your CPU if run that hot for too long.

Those temperatures will degrade his cpu quite a bit if kept there for prolonged periods

Mounting pressure could be a factor, or perhaps a problem with the pump

I don't think its bad contact or mounting pressure, I just tested this by stressing fpu to get my temps up (100C unfortunately) and I can see that the water temp is rising considerably fast. I think that indicated that heat is being transferred well. But I don't know how to see if the pump is bad, I dont hear any odd noises and I Imagine if it was bad then I wouldn't be able to do anything at all let alone test it like this or play games. It may also be worth mentioning that my idle water temp is around 30-32C if my memory serves me correctly.

Mine was delidded and idles at about 30°C usually. The max in games would normally be somewhere around high 60's to 70°C with a 240mm Arctic Liquid Freezer. I have mine at 4.8GHz and it needs around 1.32v, but if I dial it back to 4.7GHz at 1.25v it runs a few degrees cooler.

 

EDIT: These are my HWMonitor temps at 4.8GHz after running Cinebench R20:

Voltages... At least for under load. Idle is really nothing to worry about, but you should be able to drop load temps when you limit how much voltage CPU can draw.

A few things I have tried. 

  • delidding again and re-applying thermal paste
  • re-applying thermal paste on the IHS
  • Cleaning Radiator
  • Switching around pump SATA power connectors.

While I was thinking about what to do I switched my SATA power connector that goes to the water pump and used a can of air to clean some of the fins on the radiator.

 

This saw an improvement, so naturally i took the radiator out (because it was very dirty in the places i could not hit with the duster) and proceeded to clean the entire radiator.

 

Upon Re-installation i found myself back where I was with temps. In gaming it is arguably lower, but I just feel like it could be better as I am still hitting 80-95C very frequently. 

I still max thermals on Aida64, and other stress tests.

 

While cleaning the radiator I could hear the water moving around and making noises. Are small air bubbles in the Radiator a bad thing? I'm not too familiar with this.

 

As for the Vcore suggestion I tried that, However my Motherboard does not support tinkering with my processor (B150M Pro-VD)

 

I am also now noticing Idle water temps of 40C. I'm in the Military and live in 29 Palms in the barracks and I understand ambient temps result in higher water temps etc but I don't think that My room is THIS hot.

What is your Coolers Water temp? and ambient temp

My current cooler doesn't monitor the water temp, but the IR thermometer I have measures about 23°C at the front fan intake and after running Cinebench again I got temps 1°C lower than that picture.

Thats unfortunate as it would fix this. Voltage control is available with Z- and H-series mobos, even for non-K CPUs.

The motherboard must be setting the vcore must be crazy high for the temps to be that high at stock clocks, I wouldn't be surprised if it's giving it over 1.4v. Delidding brought my temps down by at least 15°C, I used liquid metal under the IHS. Before delidding, my temps were really high, but at stock they still weren't as high as yours, even despite the fact that I was only using a Cooler Master Hyper 212 at the time.

 

This is mine after 5 minutes of AIDA64. I have AVX offset set to 2 so it was running the stress test at 4.6GHz, but the only reason it even got as hot as it did is because my fan curve is very silent.

I have monitored this during a day of gaming. I watched it get as high as 1.356. Would lowering to a max of 1.25 really be that much of an improvement on my thermals? If so I suppose Ill need a new mobo soon.

Thank you for this information. Will be very helpful in the near future. haha

The vcore does make a massive difference to the temps. You should be able to get 1.2v or less at stock speed but each chip varies.
