brand is quite new to the Hardware Enthusiast scene, although they have been around for quite some time; it is only recently that their products have started to appear in our online shopping lists. We previously reviewed their Zalman look-a-like Socket A coolers here
and found them to be a valid alternative if you are on a budget.
The MegaCool heatsinks on display today cost even less and are aimed at replacing the Stock AMD cooler with a budget friendly better performing version.
There are 2 different versions available of each sink, the "+" in the name means that you'll get a speed adjustable 80mm fan (1500-3000rpm). The rheostat is very small and you need a small screwdriver to adjust the fan's speed. Not ideal if you want to change it a lot.
The difference between these two fans is the ball bearing; the "b" version has 2, the cheaper "c" version only one. Both MegaCool II+ & III+ are equipped with the B version. I could not hear the difference.
The fans come installed with finger guards, but the screws used are too long, spacers are used to make them fit more tightly, when the fan starts trembling this will increase noise, although not by much, but everything adds up.
Stock AMD ..………… MegaCool III+ ……..…… MegaCool I+ …..……… MegaCool II+
MegaCool I & II comes with copper inserts, II's a bit larger and the aluminum fins are bit higher also. The III is made out of copper and sports fine fins:
The finishing on these heatsinks is okay, the base is not perfect and lapping it might prove useful.
