Socket Cooler round up

Alpha's PAL8045

The Alpha brand of heatsinks are known for their quality, if you have a good eye you will notice that the copper inlay in the heatsink hasn’t been pressed in, somehow they have melted it into there. Alpha will not comment on how they do this but I can safely assure you that it’s the absolutely best method available… This HSF uses four holes around the socket on the mainboard, this is great because it makes sure that the HSF sits very secure and can’t fall off and destroy things; it also delivers a good pressure level against the CPU core.


But as always there is a downside and here it’s that you will need to remove you mainboard from the case when you install the HSF, if you don’t have a hole in the plate that your mainboard rests against…


Alpha recommends that you place the fan so that it sucks the air, rather than blow, so that is what I did.

With the high-pitched 80mm Delta fan it delivers temperatures that almost makes my water-cooling rig look bad, and with the quiet Sunon fan it even manages to make me satisfied about the noise level!

If you are a hardcore overclocker, you will want to put the Delta fan on and get an extremely efficient cooling setup. On the other side if you want to go the “quiet” (pun intended) way you can choose a lower specked fan and you will still get better cooling results at a lower noise level compared to the 60mm coolers in this roundup, the reason for this is that the heatsink uses 80mm fans which produce less noise due to their bigger blades, compared to a smaller fan which would require a higher RPM to deliver the same amount of air… The price, while maybe not looking cheap still is a bargain at $40 without a fan, there is a lot of work that has gone into this heatsink, and it will offer you good cooling for a long time, you just can’t go wrong by buying this HSF…


Thermalright SK6

The SK6 uses a standard clip, which makes use of two of the total six cleats on the CPU socket. While I can't understand why any manufacturer makes heatsinks that don't use all six cleats on the CPU socket this particular one isn't that bad - Since it's heaviest point is the bottom plate which is right next to the CPU, which thus isn’t causing much "over-hang", but I still don't like that heatsink manufacturers takes this approach, the cleats have been there since socket 5 - It's just a matter of using them...


If you want to see what happens if one of the cleats on the socket do break of Tom’s Hardware has "simulated" it here. The installation of the heatsink is fairly easy, just "clip the clip on". A flat-headed screwdriver is required though.


The performance of the SK6 proved to be quite incredible, while neither the size nor weight (330g) did expel the performance certainly did: out of all 60mm heatsinks tested this one turned out to be the best!

I also tested the heatsink with lower spec fans, and while of course performance is decreased so is noise, in my opinion the YS-Tech is the loudest fan you will want to have in your computer; The Delta is simply too much of the good…

Only the Alpha 8045 could outperform this HSF. But if your mainboard doesn't have the 4 holes required by that heatsink, or you have a cramped case this is your best bet, its price is also quite good; around $30 without fan.
