So, first of all, while I do have some knowledge of components, I am far from being an expert. Especially when it comes to hardware manipulation. The one who did the hardware manipulation on our PCs was my father, who died from covid-19 last year. As for me, well, I'm not exactly good with my hands so...
That being said, here's the situation. I have a desktop with an i7-5820k, cooled with a corsair water-cooler. In the past year, temps kept going higher and higher gradually.
Now, with 18 degrees ambient temperature, the CPU overall temperature reads ~70 degrees idle, and ~90 degrees at 40% load. Core temps themselves are a bit lower, at 65 and 85 respectively. Did I mention those temps are in Celsius ?...
So, here are the issues I thought of :
-1 : dust on fans
-2 : dried thermal paste
-3 : lack of liquid in the watercooling system
-4 : other watercooling issue.
I'll address them one by one :
-1 : There are two fans in that watercooling system, one easily accessible, and the other "in a sandwich" between a grid and a metal plate, which means hard to reach. While the first one had some dust on it, it was extremely thin, albeit it did dirty the cloth I used to remove the dust from it. The other one looks like it's in the same condition : thin, almost invisible dust on it, but I can't access it. While it's not very good, I think it's safe to assume that it's acceptable and not causing the issue here.
-2 : thermal paste was, from what I know, not replaced since temps were good (30-40 idle, 55-70 100% load) until one year ago. But since 2015, it should have dried up already by then, so I'm a bit doubtful. Especially since the pipe leading from the CPU to between the fans is quite hot, almost burning to the touch, even near the fans, so heat seems to be conducted from the cpu to the watercooling system...Should I replace it, and risk making a mistake?
-3 : I've read that water could evaporate from the watercooling system, making it less efficient. Should I risk opening it, probably loosening the seals in the process, and thus furthering (or creating) evaporation in the future? If yes, should I just check the liquid level somehow, and add some if necessary? Or should I fully replace it with distilled water&a bit of biocide? Where would I find those two by the way?
-4 : Is the watercooling system just not working properly anymore, especially the pump since it sometimes makes loud noises, and should I just replace it? By doing so, does that mean I would have to apply thermal paste? If that's the way to go, how do I make sure the new system is compatible with my motherboard/cpu/case? (I don't know exactly which watercooling system was installed in the first place, only its brand...)
My own guess is that the best way to solve the issue, which is also the one requiring more work&skill, is to just replace everything, watercooling system&thermal paste... If you simply agree with that, the only things I would like you to provide is how to get the right system, and point me towards a good, detailed, step-by-step, explanation video to do it...
Sorry for the length of this post, but I tried to address everything in one go instead of adding elements only if asked or even after using a proposed answer, only for it not to work well enough..
Thank you in advance for your (hopefully helpful enough for me to manage to address this issue) answers!
