Updated fan settings on H100, but CPU is overheating now.
Updated fan settings on H100, but CPU is overheating now.
Hi everyone. I'm a novice in the world of overclocking, so excuse the rookie question! I've had my system built for me a few years ago so I don't have any experience in how it's put together, recently I wanted to replace the stock fans because they're incredibly noisy. However, since replacing the fans when I run a CPU-intensive activity the core temperatures are shooting up through the roof! (The new fans are Noctua NF-F12s). Looking at the temps they jump up almost immediately to 91 and rising. I have to stop the process in order for it to cool down.
I reinstalled the old stock fans again to see if it was due to the fact the new fans are underperforming but the temperatures are still shooting up immediately, which makes me think it's not the fans and I've screwed something up in removing the unit.
I removed the whole CPU cooler in order to easily clean the radiator outside. In the process I noticed the residue of the 'thermal material' as is mentioned in the manual (pictured). Could it be due to this? A little reading on this forum makes me wonder if I need to reapply such a material in order for the CPU to be adequately cooled. Does this sound like the solution to my problem? Thanks, and sorry if this is an obvious question

You'll recognize a leak when it stops cooling effectively. Thankfully, you spotted it. Reach out to them since it might still be covered under warranty.
I’d strongly recommend taking that out of your case right away and never using it again.
You're in luck—see how near the water got to your CPU. If it had gotten through the grease and into the pins, things would have been disastrous.
The thermal paste appears to be in poor condition here. I’d strongly suggest cleaning it away completely and applying a new one. I’m also wondering about the dark spots near the edge of your CPU block—seems like corrosion as well. Make sure all connections are secure.
Thanks for your reply and your suggestion. I've ordered some thermal paste and will give this a go.
I also got a better look/picture at the block and it does look like corrosion. Is this indicative of a problem? Obviously the cooler was working fine before I removed it. I wasn't planning on replacing the unit just yet but if it suggests liquid leaking then that's something to be concerned about right?

That sounds like corrosion. It seems the pump might be leaking very gradually, with water moving slowly along the copper surface.
Well, it looks like replacing the unit would be the only practical solution, wouldn't it?
I believe you avoided needing to replace your motherboard or CPU by addressing the leaking problem. It seems only time will tell if you'll face a bigger leak and a worse situation...
I suggest replacing your cooler. If budget is a concern, I've used the good old EVO 220 in the past—it's affordable and provides decent cooling...

I believe you avoided the need to replace your motherboard or CPU by fixing the leaky issue. It’s likely just a matter of time before a bigger problem arises... I suggest swapping out your cooler. If budget is a concern, I’ve used an Evo 220 in the past—it’s affordable and performs well... Adam

Fortunately, I found this out earlier than it became worse. I’d give the chip a thorough clean with isopropyl before applying the new paste and cooler (perhaps even reducing the paste a bit).
