Overclocking i7

[Napa]

Here's a nice cooler :music_whistling: :joystick::pilotfly:.........:D

I'm not sure about I7 systems but I read on clunk.org.uk that you should not exceed 75C on C2D CPU's. For every 10C increment above 75C you lose 1 year of life of your CPU.

 

I've just upgraded my stock Intel cooler to a Zalman CNPS9500A and I can run my E8500 @ 3.8 GHZ on air no problems. I never exceed 60C on full load using prime95. I highly recommend this CPU fan it's huge. Don't use a stock cooler there inefficient.

I was just looking into this cooler. Right now my corei7 runs at 58C under load while playing black shark. You are right, the stock INTEL fan can't keep the processor cool even when it is not overclocked.

Rule of thumb for C2D CPU's is 10% OC for the Intel stock fan to keep CPU within acceptable limits for example E8500 @ 3.16 GHZ on stock Intel fan = 3.46 GHZ.

 

I love this fan it forces the hot air from the CPU straight out the chassis rear exhaust fan. Remember I never exceed 60C under prime95 heat test and I have my fan running on silent (edit fan setting is on optimal not silent) with ASUS Q Fan. If I turnt that Qfan onto performance mode I could bring those temps right down. I can't get past 3.8GHZ due to shit memory but I'm upgrading my memory to Corsair soon and with that fan I'll easily break 4 GHZ.

So just to confirm, this cooler keeps the proc at 60c with all 8 threads running in prime95?

[hitman]

4 of those cores are hyperthreading, so you should only wory about 4 cores.

Bud I don't have an i7 CPU so I can't honestly say yes or no, I can only tell you that I can run my CPU @3.8GHZ and not exceed 60C.

So the heat output of the processor doesn't change with hyperthreading enabled/disabled?

[hitman]

Not really. Its just 4 cores with hyperthreading, thats all.

Here's a review for the Zalman if you read through the users comments you'll get an idea of its cooling capabilities.

Yes it sure does , it adds about 5-10 deg C extra temp when enabled

I run with it off
