Heatsink choice for Commell LV-679 with T7500 chip.

[loaky]

I've looked everywhere! The stock cooler just isn't that great, well too small to be of any great use. I've got the board in a Nexus Psile case so there's plenty of clearance for maybe a larger heatsink. I don't really know what will fit or what to look for, as searching socket 479, socket p, or T7500 cooler doesn't bring a lot.

Any help would be great!

First off, how do you know the stock cooler isn't doing its job? What's the temperature of your T7500 when idle and under load? mini-ITX setups are generally cooled passively, which is why maybe you weren't able to find any T7500 cooler. May I suggest you just make sure the airflow through your case is good?

The airflow is quite good, an 80mm fan blowing cool air in, directly into the path of the HSF, another point is the noise from the stock fan. It idles at about 57-58 which I consider quite high, and under load it soon jumps up sharply. I've got Arctic Cooling MX-2 on there now which is slightly better than the stuff that came with it.
Passive cooling is what i'm after, so i'm looking for a larger heatsink mainly.

I wouldn't know how noisy liquid cooling is, but those temps are hot! I'm not sure if you can rely on a heatsink only.

Simple test: open your case and blow a house fan inside. If your airflow is as good as you say it is...your temps won't differ very much and you will indeed need a new HSF. If you see a big difference in temps, you have an airflow problem and need to address it.

The original question was about heatsink choice, finding a larger quieter one, not the airflow in the case. The 80mm fan blowing air into the path of the cooler is the best that's going to happen in the current case.

But what I am saying, even if you get a larger heatsink, and you don't have the airflow to remove the heat, you will end up with a similar issue as when you started. You can have the best heatsink there is, but if you don't have a way to cool it, it is pointless. You either have an issue with an inadequate heatsink (which I doubt if it is the boxed retail version @stock speeds) or you have poor case ventilation. The latter of which has to be addressed first before you can expect any cooling solution to work as designed.
