Question i7-8700k idle temp is 90-98c

[elgringoloco]

i7-8700k. I never tiried OC'ing. My idle temp is at 90-98c and I lag when I game. I tried putting thermal paste and the game lag is gone but back after 3 days. my cooler is NZXT Kraken m22. pls help. sorry for my bad english.

Your M22 is either installed incorrectly or the pump is dead as those temps are way too high and should be under 80C while gaming.

If its at 90 degrees celsius, you need to shut your computer off right xxx xxxx now before your cpu actually melts

See video installation guide and check things over. Preferably watch video on phone or tablet to avoid running your PC any longer. If cables/connectors and mounts seem to be in order i would consider asking a PC store for help.

you need a better cooler than that,

The cooler design isn't the cause for high idle temps.

Are you positive it's being read in °C and not in °F?

90°-98°F = 32°-36°C, which is right on the money.

i know that but dont you need at lest a 280 for the 9700k?

Not at all, maybe for 9900k + overclock at full load. If Idle temps are read correctly, shouldn't be this high with the cooler in use.

A 9700k is capable of @ 200w output under Prime95 small fft at 5.0GHz locked cores. A good aircooler or 240mm runs @ 250w+, so is plenty for that cpu. The 9900k/s at a 5.0GHz full lock core is looking at @ 250w so really requires the 300w+/350w+ of the 280mm/360mm AIO's, even a NH-D15 seriously struggles at its 250w+ rating.

Next to that, the 90w put out by a stock 8700k at full load is chump change, it's only under OC values with locked cores that you'll see outputs hitting @ 150w, which is more than that 140w M22 can handle.

But that's load temps, not idle temps. Idle temps have little to do with the cpu as power usage is minimal. Has everything to do with case ambient temps, and/or in this case, the possibility of incorrect mounting. Since there's no way that the case ambients will be anywhere close to 90°C, the only 3 possible, viable answers are incorrect mount, aio failure or °C/°F reads.
