Thermalright SI-128 sufficient to cool Intel Core i5 2500K?

Post by slavicVII » Wed Dec 07, 2011 10:42 pm

I'm upgrading the components in an Antec Fusion HTPC that currently has an old AMD AM2 processor cooled by a Thermalright SI-128.

There's no need for a fan on the Thermalright itself as the two 120mm fans are so close:

I'd like to keep this passive solution if possible when upgrading to a build around an Intel Core i5 2500K. Is the Thermalright SI-128 capable of cooling this processor? I've found a mounting kit for 1155 processors here that suggests this'd be ok.

The alternative I'm considering is buying a Thermalright AXP-140, but I'm not entirely sure that'd fit in an Antec Fusion, and it does seem similar in appearance at least to the Thermalright SI-128 so I'm wondering what exactly I'm getting extra for the expenditure.

I'd be most grateful for anyone here's thoughts or experience.

I'm pretty sure it will work, the 2500K doesn't use much power. Is there room for a fan on top of the heatsink, just in case it would be needed?

Given that my 2500K is cooled quite adequately by a Kozuti, which has a smaller surface area and the airflow of an 80x80x10 fan, that should absolutely work. I don't know about overclocking, mind you, but at stock I would do that without worry.
