Hello wise PC enthusiasts,
I have been using a Corsair H60 aio cooler to cool my i7 5820k for about a year and a half now. I monitored CPU temps for the first year or so and my temps were usually around 40c idle and 55c while gaming or anything of that sort. Just recently I decided to start monitoring my temps again and noticed that my temps are 60-70c(!) idle and 80-90c under load. My PC hasn't shut itself down or anything like that and I haven't seemed to have any type of performance issues, but I know there's a problem because the temps are much, much higher than before.
I took off my panel and inspected and I had a huge amount of dust clogging my radiator fins and fan, so I dusted it all out nicely and booted back up. My temps are still just as high as before. The air coming out of the radiator through the top of my case is ice cold even if I feel it while my cpu is at 85c or higher. I checked my pump reading using some monitor software and it showed my pump as running at 4400rpm and it still seems to be making noise. Could it be the thermal paste has dried up or something? Or could my pump still be dead even though it's reading at 4400rpm?
-Corsair H60 cooling i7 5820k for 1 1/2 years
-Used stock thermal paste that came with product
-Old temps were 40c idle/55c load, new temps 65c idle/90c load (or even higher, highest i've seen is 93c on a core)
-Pump reads as running at correct speed (4400rpm)
-Dusted out radiator fully, temps stayed just as high
-Air coming out of radiator is ice cold, block over CPU is hot to the touch
-bad thermal contact? maybe my paste is no good anymore or something
-bad pump? maybe pump is gone even though it reads at correct RPM
Any help would be very appreciated. I'm looking for some general advice before I order thermal paste or just a new cooler altogether.
Thank you for your time! :-)
