Random temp spikes

[ParZival1994]

im getting random cpu temp spikes in my cam software. itll be sitting at 39-42 degrees C then spike to 80+ degrees C. anyone know what could be causing this?

let me know if you need any other info. Thank you!

It's kind of what the 7700k does in my experience. It runs hot and has these weird spikes. Mine does it as well.

Could be something like a malware that's coming up and using cpu resource every once in a while.. i had something like this before
the other thing that could cause this is defective liquid cooling or just old AIO that doesn't have enough liquid inside or with other words the liquid has evaporated thus leaving air inside the system 
my 4 year old AIO had maybe half of the liquid left inside and would run like 45 degrees idle and every once in a while would rice up to 60 but that takes like 10-15 minutes to rise the temperature. 
Also look at your thermal compound if u have too little maybe it will be good for like idling and maybe not even noticeable while idling but when u put a stress on the cpu it will rice the temperature fast because not having enough thermal paste will restrict thermal conductivity.

I'm about to order a new cpu cooler to try that. should i use the stock thermal compound on the cooler or buy third party compound?

If you don't mind voiding your warranty, delidding your cpu and replacing the TIM under the IHS with liquid metal will resolve this issue. Its just background proccesses putting load on the CPU and the poor TIM being unable to dissipate it to the IHS fast enough. My 7700K also used to do this and it was super annoying since it would cause the fans to go beserk if I didn't have sufficient hysteresis.

im pretty new to building my own pc. delidding is a bit out of my depth for now. maybe in the future ill try this. Thank you.

Delidding Sky-Kaby-Coffee Lake CPUs are super easy if you have a tool like the delid-die-mate. People drop their load temps by about 10~20 degrees using liquid metal (e.g. thermal grizzly conductonaut). The liquid metal application is a bit daunting at first but also not a big deal.

 

Some photos from the time I delidded my 8700K (practically the same as the 7700K). You can just see how much thermal paste is caked onto the die, nicely acting as a blanket for the temps.

 

 

Hello thermal goop.

 

cleaned the silicon glue off by scraping and the thermal paste with isopropanol.

 

Applied a drop of ThermalGrizzly Conductonaut and spread it with included q-tip.

 

Did the same for the IHS, slight more generously since cannot get the exact mount location by eye. Made a right mess of applying a thin line of siliccon glue, but just enough to hold it down is fine.

 

relidding. 20 minutes.

Yo, that's pretty cool. ill look into these, thank you for the info. this is a huge help.

Seems like regular cpu spikes to me.
