I my cpu was i5 9400f . I just bought and installed i9 9900k. Now, my cpu temperature is 90 degree to 100 degree when i play games. I have tried reinstalling thermal paste, but no changes. Now, I researched in the internet and found that I need a powerful cpu cooler . Please suggest me a cpu cooler for i9 9900k which will fit in my hp omen desktop.  My budget is 30 to 40 pound .  Please help me. I am confused which cpu fan should I buy for this motherboard .
