I7-7700K 4.2 ghz high temperatures!

Hello i have the I7-7700K 4.2 ghz CPU, its on turbo running at 4.5 ghz, my cooler is the H110i GT.

My cpu temps are running really high. When i open google chrome, i see spikes in temperature going op to 70 degrees for a short amount of time.

When i run Cinebench and test my system, my cpu hits temperatures going from 70-97 degrees. What should i do?

Thanks in advance.

That's about right for an overclocked 7700K in AVX loading. What voltage are you running? Voltage makes a huge difference to power consumption.

Here's some things to try:

  • Reduce voltage as much as possible (while retaining stability)
  • Make sure your AIO pump is set to full speed 24/7 (No DC throttling)
  • Set an aggressive fan curve to set max fan speed at 60°C
  • Replace the thermal compound with quality TIM, such as Arctic MX-4

Where in bios can i reduce voltage.

Another question does the high temperatures affect my fps when im playing, for an example thermal throttle?

I just realized this isn't overclocked. I was thinking of the 6700K.
You can still undervolt it, but I'd pursue the other options first.

Okay so those high temperatures for a stock i7-7700k 4.2 ghz with intels turbo boost enabled so 4.5 ghz, are way too high and unstable?

It's the cooler's job to keep the chip cool. A H110 GT should have no issues with a stock 7700K.

- Okay thanks alot, do you think those high CPU temperatures makes my FPS lower in games?

- If i can get a stable TEMP, would overclocking it then could improve my fps by a lot?

It won't have an effect on FPS as-is, the CPU is almost thermal throttling under Pure AVX synthetic load. No game loads like this.

 

I can make no claims on if OC'ing will help your FPS, without knowing a lot more details about your setup, games, and settings.

 

Silicon Lottery claims 100% of 7700K's hit 4.6 GHz, top 1% can do 5.1 GHz. (All Core). Stock is 4.4 GHz, inc. turbo, no power/thermal limits.

 

This means at very very best (synthetic), you're looking at 5-15% improvement. Again, no game will show this level of gain.

If I were to guess,  if you're 7700k was anything like mine,  it's the TIM between the die and IHS. After delidding my CPU and applying some liquid metal my Temps dropped from high 80s when doing benchmarks or other cpu intensive tasks to mid 50s.

I haven't touched the voltage settings, do you think i can lower them a bit? And do some modifications?

7700k was notorious for bad TIM, I don't think you'll get very far without modifications. At least not the type of results you're probably looking for.

Okay what modifications could i do? Im willing to pay if you can help me get my temp lower and overclock it.
