I just built a rig for the first time and i chose an corsair H50 cooler. My temps at idle are... well 5 degrees lower than the stock cooler. at idle its at about 30-32 degrees celsius at 75% load my temps are about 58. Anyone know what i may have botched? I did put AS5 on it prior to installation. Im running a i5-2500k with a sabertooth p67 mobo...

Is your cpu overclocked? I know AS5 takes a while to cure so you may see a 2C to 5C improvement in temps after break-in period.

Did you remove the stock H50 paste or just slap some AS5 on top of it. If you just slapped it on over the stock stuff you got to much on.

1. AS5 takes 200 hours of thermal cycling or as much as a year under normal usage to cure.

Quote :

Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

So by my estimation of this statement it would take almost a year of normal use to properly cure the AC5 compound, or almost nine days of continuous power cycles to meet their recommendation.



2. The H50 isn't among the top coolers.

http://benchmarkreviews.com/index. [...] itstart=11

Prolimatech Megahalems - 24.9
Scythe Mugen 3 - 27.0
Corsair H50 - 29.3
Intel Stock - 38.5

As the AS5 cures over time, temps will improve ..... but will fall about 5C short of the top coolers.

H50 is kinda almost watercooling. Weak block for transferring heat, very small rad. It's all about physics. You still need to remove heat by air cooling over the fins in the air cooler or the radiator.

The H50 is proven to be less capable than a top air cooler. It's not real watercooling. Real watercooling costs MUCH more, because the radiator, pump, block is quality. The H50 isn't quality. Seen many learn this important lesson. You just did. Much info on the web on how you can make the H50 better. Mainly massive push/pull fans. Not enough, ahh well....Save your pennies, $150 min is a good start. This is a almost weak real watercooling setup, okay rad (not great), almost great pump/res setup. Decent block. Still a great start, will give great CPU temps no matter what rig you have.

Google XSPC Rasa setup.

Real watercooling BTW........

conumdrum is right. an h50 won't make miracles happen but there are things you can do to improve those temps. look up a product called indigo xtreme. its pretty incredible. you'll likely see a change of about 7 degrees. i just put it under my supreme hf and my 950 hasn't crossed the 60 degree line at 4.48ghz. good stuff

wow this stuff sounds really interesting. Thanks for sharing.

Yeah, H50 is pretty weak, the H70 is a little better...they fixed some things for a little better performance and longevity. H50 is known for weak/failing pumps, leaks and marginal performance.

Conumdrum has stated some great points that often get missed for first time users that don't do much research.
