Hi, I've recently noticed something interesting about my H100i that I bought about 3 or 4 years ago. I've been having relatively high temperature for a while, so I've blown out all the dust, reapplied thermal paste, and made sure the cooler is mounted properly, but my temps are still relatively high for my i7-4790k. However, I recently noticed something that brings my temps down.
I noticed that by physically hitting the top of my case close to where the radiator is mounted a few times, my temps drop instantly. A few light pats seems to do the trick, and I'm just so confused as to how this is even working. The effect is dramatic, I notice my package temps drop more than 20-30c instantly. The image below shows my temps right after I hit it. I have to do this at least once a day since the temps rise back up after a few hours.
Is this just an issue of my H100i being old and needing to be replaced due to blockage and buildup? Is there anything I can do so I don't have to keep abusing my poor PC? Thank you for the help.
