I currently have my A8-5600K running with the stock HSF. It seemed as though idling was even rather high but after adding a couple small case fans idling would drop to about 41C.
However, recently I got curious what the temps would get to under some load. I ran an HD YouTube video and if the CPU hit 30% utilization temps would raise between 60-62C.
So then I thought I'd run a full load with Prime95 and temps jumped to 90C under 5 minutes. I decided I shouldn't let it run much longer and turned off the test. I decided I'm not messing around anymore and have ordered a Cooler Master Geminll M4 but I have to wonder if the stock HSF is really that bad.
I find the mounting for the stock HSF to be questionable as it's hard to keep it square as there seems to be a lot of movement when pushing down the clip. Just looking for opinions. I've read comments before where people have gotten really good temps with the stock HSF.
Only thing you can do is unseat, clean the processor IHS and HSF with isopropyl alcohol and a lint-free cloth/rag/etc., put a dot in the middle of the IHS and reseat the HSF.
The stock fan may not be suitable for overclocking, but it should definitely keep around 60C in Prime95 at stock settings.
Well it definitely runs much hotter than 60C very very quickly. I was going to re seat the stock HSF but I figured I'd go with something better than stock if I'm going to do it. I must not have seated the stock properly or either re adjusted it too much after the fact.
I should also make clear that I am not overclocking at all.
