Question CPU is overheating

[SHAPELESS_STEEL]

First post on here, still relatively new to PC building, had a build that was working well but upgraded and the CPU is now overheating up to about 99 degrees, can't figure out the reason for it, I don't have a disk drive so I haven't updated anything and the internet isn't connecting so I haven't tried that, my current build is a rear fan blowing inward, 2 top fans blowing in and out, 2 fans on the back of the radiator blowing out and 3 fans infront of it blowing out as well, an i7 8700, MSI mpg z390 MB, Corsair rgb ram 2 sticks 8gb each at 3000 MHz, gtx 1070, 650 watt power, nzxt kraken x62 CPU cooler

What thermal paste did you use?

EDIT: would also maybe make your fans more even in places rather than having two in a spot using intake and exhaust, keep it the same.

I actually intended to have both top fans blowing in but I just mistakenly put one in wrong and haven't changed it yet, I used insignia thermal paste,the stuff you get from best buy bc it was convenient, if you have a better solution for the fans I'm all ears, I as well had the same set up for the last build but less fans, hottest it had gotten was maybe 70 degrees

I mean probably best to try to switch those fans. I don’t know much either but I’ve watched a lot of TechSource videos!

The best thermal paste for top tier temps I’ve seen on TechSource and others saying it does really good and it underrated which I will try next week myself is : Thermal Grizzley Kyronaut

You can get a solid 5.0GHz with good temps is what I’ve seen and read and watched.

EDIT: switch those fans as in making them all the same ways and equal so it’s not just slamming air every which direction.

Did you connect the x62 correctly, and can you verify that it is working?

and that the power is connected to the pump connector mentioned in page 37

Make sure the cpu fan is well screwed if that doesn't work clean and reapply heat gel if neither work you probably need a new cpu cooler.
And fix the fans
ps: don't put too much heat gel

It is secure and it was working yesterday, it's less than a year old, at the moment it is connected to the CPU fan but when I first booted it up I had it connected to the CPU pump and was still overheating, device manager say it is working and it does light up, I will try tonight to reapply the thermal paste and see how that does

I also intend to switch all the fans around tonight and have the front as intake and top and rear as exhaust

Small point to add. When applying thermal paste, the old "more is better" practice is VERY BAD. Look up actual instructions from the paste maker for the actual type of CPU chip you have, and use that much. For example, I've seen guidance for smaller CPU's to apply a blob "the size of a grain of rice", then place the heatsink on top and smear it around a bit before fastening the whole thing down tightly. Other CPU's require more paste. Sometimes there's a different procedure recommended for spreading. The background for this is that, while the paste really helps to carry heat from the CPU case top to the heatsink block by filling in minute graps in the contact area, it also is not a perfect heat conductor. Thus a too THICK layer of paste actually acts like an insulating layer to some extent.

I put slightly bigger than a grain of rice, maybe 2 grains worth, always heard that's what your supposed to do, so I'll definitely be looking into that, wasn't aware too much could do that, thanks for the advice

Okay so I switched my fans, front as intake and top and rear as exhaust, switched the CPU cooler cable back into the pump socket, reapplied thermal compound using a grain of rice amount and it is still overheating, CPU running at 1.058v, I actually heard the pump itself running as it first started up after I put new compound, and I went into bios, put all fans and pump at full blast, it is a lot slower but still getting to 100 degrees, tried to check to see if there was maybe an over clock multi core anything in bios turned on but didn't find anything

Thank you to everyone who tried to help, I now have a lot of useful info for the future, finally found the issue, turns out my nzxt kraken x62 CPU cooler stopped pumping or something along the lines, put the cooler that comes with the i7 8700 on and it sat at a stable idle of about 36c, 10/10 would not recommend this water cooler to anyone, is there a water cooler anyone would recommend? Or should this cooler be strong enough for long hours of gaming?
