IHS on Core i5 damaged, reason of high temps under AIO watercooler?

VexedDegree33 · Jul 22, 2016

Hi, the problem is that about 1 month ago a friend of mine hit my CPU tower aircooler and one of the pins for the mount broke, thus not making good contact with the CPU and reaching temps of up to 84ºC under load, so I changed the cooler to a Arctic Liquid Freezer 120, but I noticed that the heatspreader on the CPU was dark colored on some spots (the ones where the old cooler lost contact i assume).
Now I'm getting temps ranging from 34 to 41ºC on idle and up to 64ºC under heavy use. Maybe I'm biased because my old 35W tdp i3 2120T was always sub 40ºC, but I find those temps a little high because another system I have with an FX-8350 OCd to 4'8 GHz is running 46ºC under full load on a Corsair H100i v2. My thermal compound is Arctic MX-4 by the way.
Please help as I don't know what to expect from the i5 3330, thanks in advance

Intel and amd don't read the temps the same way. One of the more accurate ways to read amd cpu's is using overdrive which I believe gives a thermal margin (how many degrees until it reaches throttle limits). 64c under full load isn't abnormal for an i5 though it depends on the program you're using to stress test it. Thermal compound has very little effect, 1-3c at most between most thermal pastes.

Your assessments are a bit all over the place, comparing an air cooler (make/model not listed) to an arctic liquid freezer 120 compared to an fx 8350 with a completely different cooler. None of the temps will really correspond with one another with all of those variables.

Have a look at the intel temp guide to give you an idea of temp ranges, ambient temps and how to stress test using p95 v26.6 small fft's (not the latest version).

Temps are relevant to the specific brand of processor, there's no one spec like well 46c was good for an 8350 so that's where an i5 should be. Amd cpu's are difficult to get accurate thermal readings from even by amd's own software and the fx 8350 tends to start thermal throttling at 65c vs around 100c for an i5. The tdp (thermal design power) gives a bit of a hint as to how much heat needs to be removed from the processor in watts of heat.

The 2120t was only 35w tdp where the 3330 is a 77w tdp design and the 8350 is a 125w tdp. The higher the tdp the better cooling solution it needs. For example an air cooler like the 212 evo is designed to displace up to 180w of heat. The tdp are averages and can be assessed differently by the companies but should be at least ballpark average under load.

Thanks a lot, I'll do that, but I feel that I'll go get a new case as well today, it's never bad to have mor airflow inside the case, any good case that you could recommend? I have around 60/80€ to spend on it as I don't want to burn money right now, thanks!

64 under load is decent for that cooler on that cpu.
