Question High idle CPU temperature

[SMund93]

Hi all,

I've just updated to Windows KB4497165 and have noticed that my CPU temperature reaches 70-75c, and it stays like that for about 5 minutes when idle.

I understand this is normal when the CPU is playing games (that's what I use the PC for). It does stabilise and stay around 30c when idle.

I was hoping if someone could advise whether or not this is a CPU or Windows issue.

The CPU I use is Intel Core i9-9900K Retail - (1151/8 Core/3.60GHz/16MB/Coffee Lake/95W/Graphics

The cooler I use is a Corsair H100i 240mm dual fan which I've used since 2014.

does it do malware scan on idle?

does it do malware scan on idle?

I'm not sure, how would I be able to check? I do load steam on startup but this issue only started happening after updating to the latest Windows update.
