SUMMARY: An interesting entry from a new watercoolng company.
The good guys at Blue Cooling were nice enough to send a sample of their peltier waterblock, model MPP85W. Blue Cooling is a new entrant to the watercooling market.
The fan is an Everflow Model #R127015DU – a 70 x 15mm unit rated at 26 cfm @ 4200 rpm. I found it to be tolerably quiet – I measured its noise at 62 dBA with a Radio Shack sound meter 8″ from the fan’s intake, substantially less than a Delta 38 (about 69 dBA). It’s also safe to use a motherboard fan header.
In summary, a fairly conventional aluminum extrusion heatsink with a very secure and easy to use clip.
The SLK600 was first tested on the CPU Die Simulator which gives results that are unaffected by motherboard influences. I then tested it on an Iwill KK266+ and Shuttle AK31, modified to read AMD’s on-die diode, as an example of what users might see on their systems.

¹In-socket thermistor per MBM
C/W = Delta / CPU Watts
Interpreting C/W: For every watt (CPUw) that the CPU
consumes, the HSF will limit the CPU’s temperature rise to (C/W x CPUw)
plus the temperature at the HSF’s fan inlet. For example, at an ambient temp of 25 C, a C/W of 0.25 with a CPU radiating 50 watts means that CPU temp will increase 50 x 0.25 = 12.5 C over ambient temp, or 37.5 C. The lower the C/W, the better.
Die Simulator results place the SLK600, with the ultra-noisy Delta 44, in the top rank of heatsinks (Heatsink Ranking). With the more tolerable YS Tech, the SLK600 ranks among the best of heatsinks tested.
Interestingly, the difference between a relatively quiet YS Tech 26 cfm fan and the noisier Delta 38 is not that great. Users might consider using a rheostat on the aggressive Delta 44 or Delta 38 to moderate noise as requirements dictate. For users seeking superior performance at low noise levels, the SLK600 with a 26 cfm fan looks promising.
Thanks again to Blue Cooling for sending this our way.
