Introduction

Today we have something interesting (to me at least) on the test bench. I just converted over to a socket 775 rig and I’m very curious if there are any coolers out there that can cool this thing down. Personally I will run it watercooled soon but in the meanwhile I want to see how this Hyper 48 cooler can perform compared to a stock cooler.

Everything was well packed even though the plastic was a little cracked in one place. On the side of the box we can see the specifications that we have here above also.

You can run this on pretty much any setup as you can see in the specs (Socket 478/754/940/939/LGA77) so alot of different mounting kits are needed for this cooler. The cooler itself is pretty big and heavy and therefore the mounting kits are well made and well planned so you don’t get that heavy weight on your motherboard when you have it mounted.

4 heatpipes go up from the core of the cooler to the top to maximize the fans cooling capacity. This is a good way as you move the head up through the heatpipes and the fan can cool them of and get the hot air out of the way.

The fins are straight and well done except I seemed to have some bent the fins on my cooler that I got. A 92 mm fans is supposed to cool this of at 18.5dB and 1400 rpm. The fan is not loud so I cannot complain about that at all even though my ears are sensitive to sound.
