hi guys, i had a weird *almost* calamity today. I have a ryzen 7 1700 running on a MSI Pro carbon with a kraken x52.

Basically everything was running fine, i shut down and restarted when the temperature absolutely shot through the roof and the fans maxing out. after a minute or so it shut down. At this time, i didn't know it was so hot so i restarted and opened event log and nzxt hue before it shut down again. sure enough, there was kernal-error 41 and the temps were over 100 (it usually runs at 35ish idle and 60ish under load)

Anyway, I cleaned and reapplied the thermal compound (arctic MX-4, I believe I used MX-3 previously) and now everythings tickety-boo again, in fact temps have gone down a bit, 30ish idle and 50ish under load.

My question is: does thermal compound really fail THAT quickly? i can't understand how it was running fine one minute then SO hot the next. i literally had no warning signs. I am assuming that this was the problem seeing as reapplying the thermal paste and running ccleaner is the only trouble shooting i did!

Thanks for any thoughts

It's possible an air bubble or something got stuck in the pump/CPU block, and when you took the cooler off to reapply thermal paste the air bubble was able to move out of the pump.

Thermal compound shouldn't really need changing before like a 3 year mark.

possibly, but its been up and running more or less 24/7 since I built it 5 months ago.

I did have some work done which created a lot of brick dust, I wonder whether some got in and dried the compound out maybe?

If your computer temps going down then thats an good sign my temps was hitting 75 when gaming but tested out youtube link and it went down to 50 maybe you should try it out. My comp is shutting down randomly and i still trying to find answers!

Also I will do an cleanup on your case make sure there no trapped dust or anything on the fans

No, that absolutely wouldn't have been related to the thermal compound. Compound doesn't suddenly fail out of the blue. Dirty fins on the radiator also wouldn't make that much of a difference.

Most likely, your all-in-one cooler's pump stopped running for whatever reason. The pump might be failing, as seems to be common with all-in-one liquid coolers, or maybe a connection just came loose or something. Another possibility could be that the cooler popped loose from the CPU, but I think you would have noticed that when removing it to change the thermal compound.

I'd already cleaned out all the fins and fans with an electric air blaster when the work was finished, so it was/is pretty clean in there. I've got a glass side so I am a bit OCD about keeping the dust down simply cos it looks so horrible.

It was so sudden I think you are probably right about the pump failing. I really hope not, i've only had it a few months! This is the first kraken I've had so not had much experience with how stable/durable they are.

That definitely seems to be the case, its been running all night with no issues.

It does beg the question though, why didn't NZXT's CAM software warn me something was wrong? It managed to load before the PC shut down on two occasions.

I'm not sure it's the software's job to warn you.
The CPU decides when it gets "too hot." In theory a CPU can get much hotter if it was designed for it. (and there are CPUs today that can't get as hot yours can)
If you're constantly monitoring your temps like with an on screen display software or a 2nd monitor with temp software on it, you can see when your temps get too hot.

ok so this happened again and I've come to the conclusion it is indeed a dead pump. Amazon have got loads of reviews saying exactly that - pump breaks after a few months. so while I'm waiting for the rma (nzxt have awful reviews in this regard as well) can anyone recommend a decent cooler for a ryzen 7 1700? I'm back with the wraith and getting around 75 degrees under load.

Cheers
