I reapplied thermal paste and reseated the aio this morning moving fans around. Will reseat the aio and reapply thermal paste tonight. Its hard to gauge whether it is a good solution because it happens far and few between. Thank you for your help!

Pump is running at 5000 rpm

So I just built my new pc recently and it was working great, then all of the sudden I just closed out a game and my cpu fan ramped up to 100%. My temps were around 65c while gaming before this so I know my cooler works. I opened openhardware monitor and saw that my cpu was pinned at 100c. Felt the air coming off my aio and it was cool, no heat other than maybe 40c worth, felt normal. So I took another fan and sandwiched my reused alienware aio with a push pull, and updated the bios (maybe it was a faulty temp reading and a bios update would have fixed it idk?). I didnt have the problem after that for maybe 5 days. Then since I have 2 new fans coming (because I was sacrificing both my case fans for the rad and had to jank on a 95mm as a makeshift case fan), I took one of the alienware fans from my alienware r6 and put it alone on the aio and put the case fans back, since it was a higher airflow fan. The same thing happened while I was closing a game, my fan ramped up to 100% and my temps were at 100c. For thermal paste I used corsair TM30 and applied enough. Does anyone have any idea whats going on? Is my cpu just giving faulty temp readings? Any solutions? Edit: This only has happened a total of 4 times in the past 2 weeks with the most recent being today. Like I said i had a stretch of 5 days where I had a push pull and it was fine. After a restart it all goes back to normal. CPU: i5-9600k Mobo: ROG Strix b365-f gaming AiO: Alienware Liquid Cooler

I bought a NZXT H510 case that comes with 2 fans. I'm reusing my Alienware all in one liquid cooler and so I have 1 fan as an intake and 1 fan on the rad as an exhaust. I want to reuse a fan from my alienware case but the fan cable is short. I have a front panel extender for my motherboard that has the 4 pins I need lined up and it looks like it should work as a fan extender since its just cables. Would this work?
