Upgrade from the stock CPU cooler that came with your desktop or server. The MASSCOOL 5R057B3 heatsink and fan assembly is designed to affordably lower the operating temperature of your processors, from AMD Athlon MP up to 1800+, Athlon XP up to 1800+ and Duron up to 1.6GHz and Intel Celeron up to 1.0GHz and Pentium III up to 1.4GHz.

The base and high-density fin array are made of pure copper to draw heat from your CPU, quickly spreading heat out to be carried away by the 4,800rpm 60mm fan mounted at the top of the assembly. Its low profile allows it to fit in tighter spaces such as slimline cases or rackmount servers.

A thermal-grease pad is already applied to the copper base; simply remove the cover from the pad, clip the cooler to your motherboard and connect the 3-pin power cord to your mainboard.

  • newegg Pure Copper Design Pure, high-density copper maximizes heat absorption and transfer for amazing cooling abilities.
  • newegg 1U Rack Mount The Masscool 5R057B3 is compatible with the 1U rack mount system to support the AMD Socket 462 and Intel Socket 370 platforms.

4 out of 5 eggsOn PIX 515E CPU

Pros: Very solid copper heatsink

Cons: Fan seems a bit cheap, but heatsink makes up for it in my application.

Other Thoughts: I used this to upgrade a PIX 515E from a 200MHZ CPU to a P3 1000 CPU, needed a better heatsink solution.

3 out of 5 eggsShort lived

Pros: Quiet, cools effectively.

Cons: The fan on mine lasted a year and 2 days. Not good.

Other Thoughts: At the price, annual replacement is affordable - but I don't want the hassle. Nothing wrong with the heatsink, I may just stick a case fan on it instead of buying another cooler.

5 out of 5 eggsGreat heatsink!

Pros: Very low profile! Solid copper heatsink! Good value for the price. Fits motherboards that will not accomodate the late PIII Intel oem hsf.

Cons: 60mm fan. Some are quieter than others but due to their size and the necessary rpm's to move sufficient air, they are all noisy.

In fairness, if the heatsink were large enough to mount an 80mm fan directly, it wouldn't fit most socket 370 motherboards.

Other Thoughts: I used an adapter and an 80mm fan with this heatsink. The low profile of the cooler allowed room for the fan adapter without making a structure that blocks airflow in the case.

Tests have shown that when the heat sink, adapter and fan get large enough to block airflow inside the case (or disrupt the intended airflow pattern), there will be little if any reduction in CPU temperature compared to the heat sink with the stock fan. The only gain will be a quieter computer. When the heat sink with adapter and fan do not block or disrupt case airflow, a reduction in CPU temperature can be realized in addition to the reduction in fan noise.

I did not experience any trouble with the retaining clip/strap. Yes, it was a little stiff but it wasn't so stiff that I was worried about cracking the motherboard when installing the heatsink.

2 out of 5 eggsway too loud

Pros: Cools your cpu very well

Cons: LOUD AS HELL. i was amazed at how loud this was compared to my stock fan. good lord. i actually bought this fan because it had a lower dB rating than a lot of the other fans i looked at, while having a high cfm... i'm pretty sure they lied here! :)

i'd definitely return if i wasn't so lazy.
