I7 7700K HUGE DIFFERENCE IN CORE TEMPERATURES

harvey.l12 · 14 Dec 2017 at 21:04

Hi All,

So I have a PC here with an I7 7700K CPU and when idle or in a game or anything stressing the CPU a little the core #1 and #2 seem to keep spiking in temperature around 20c every few seconds.

See Image Here - https://ibb.co/cyXj4m

It also looks like these 2 cores I mentioned are receiving more load than the others for some reason? any ideas why and how I could fix this? Is this normal.

I have a H100i V2 as the cooler which should be working sufficiently as its only ever these 2 cores that keep spiking causing my fans to keep kicking in faster obviously becoming extremely annoying. This is how I noticed the issue.

I am wanting to know if there is anything I can try from your guys experiences and if anyone has ever seen this issue. I can re seat the heat-sink at the weekend but was wondering if anyone has any other ideas that I can try before doing so.

Any ideas anyone?

I Have not tried this yet but will check this tonight as I will have time to do so now. I can't remember needing to add any of my own thermal paste on the plate as it came with some on stock but I might wipe this off and re-apply with my own.
I will update once I have re-seated the heat-sink for the cooler.

I've re seated my CPU as the paste wasn't greatly spread from the paste that comes with the H100i V2. This helped a bit but I noticed that the intel CPU software was taking priority over my V-CORE so I have reduced this and now temps are good again. Still spike but no way near as high and temps only reach 60oc when gaming now.
