why so hot?

paradisiac · 29 Jun 2011 at 16:44

ok, got my i5 2500k yesturday and fitted it, i whacked the auto oc up to 4.4GHz (CPU-Z said vcore was 0.9** idle and 1.3** under load) and it is stable although temps are a tad high for my liking 75-79c during prime.
the 4.6GHz was also stable but after 20mins of prime it hit 83c so i stopped.
i think both these would be achievable with some voltage settings, but i just wanted to play games and try out the chip so didnt have a play. will have a better look on sat when i have a day off.
why does it get so hot? is the freezer 7 really poor or is this normal for air cooled 2500k chips?
when gaming they get to the high 50s to low 60s.

Those temps are to high. If you haven't already done so, you should refit that cooler and see if that helps.

And your voltages look fine, plus 4.4GHz isn't really pushing your chip to hard for the temps you are getting.

ok will try to refit it over the weekend when i have more time. what are the usual max temps?

Stay under 80c, but I like to have my temps in the mid 60's range when under prime 95 stress testing.

freezer 7 imo isn't exactly a big overclocking heatsink. Mild overclocks are ok but once the vcore is cranked up you need some heavier artillery. I got a 78C max temp on my 2600K at 1.39v 4.8Ghz with my NH-D14 with Intel burntest on Monday.. when it was 32C indoors.

ok, well 4.6GHz went over the 80c in prime, so i stopped it straight away.
what do you use to measure the temps?

Justintime · 29 Jun 2011 at 17:47

Coretemp or realtemp.

yeh i think an upgrade is next on my things to do. i got the freezer 7 for my old 555 and it handled that ok, i guess this is a step too far for it.

Because you haven't got a great cooler you have a good cooler.

get cpuid hwmonitor it does all your temps, also if you can afford the best cpu surely you can afford a desent cooler

YES! i was shocked when i bought a freezer pro 7, it was ONE degree cooler than the stock cooler! i reseated it three times becuse i could not believe it was an aftermarket cooler that was so poor!

thats not really how it works. everything has been bought in stages, and a decent cooler is £40+ so thats still a lot of money.
i will upgrade it when funds allow, but at this point it doesnt. if i had a spare £40 then i would have got a 2600k and not a 2500k surely?

is it the fan that lets it down, or the design?
