Very good heatpipe – Joe

SUMMARY: Very good performance at 5000 rpm, although somewhat noisy; lower speeds quieter but performance muted.

Size: 88 x 67 x 74mm; Weight: 375 grams; Fans: 5000, 3500 and 2300 rpm.

The good guys at ICEe Computers were nice enough to send a sample of the CpuMate Heatpipe, model #D130HA4. It comes in three versions: 2300, 3500 and 5000 rpm fans – the one I tested has the 5000 rpm fan.

The construction is interesting – the heatsink is actually made from two halves:

The bottom half has embedded heatpipes in the base, with cooling fins; the top half serves to cool the heatpipes:

Looking at the heatsink from the edge, it looks like the top and bottom are mirror images. Top and bottom are joined by a crimp joint on each side:

One interesting feature (I don’t know if this is in all versions) is a hole in the base which can be used for a thermal probe:

The fan is a Bi-Sonic Model# BS701512HH – a 70 x 15 mm unit rated at 40.5 cfm @ 5000 rpm, 41 dBA¹. Other fan speeds are rated: 28 cfm @ 3500 rpm, 31 dBA, and 19 cfm @ 2300 rpm, 23 dBA. At 5000 rpm, it’s not particularly quiet – I measured its noise at 63 dBA with a Radio Shack sound meter 8″ from the fan’s intake, less than a Delta 38 (about 69 dBA), but definitely noticeable; at 3500 rpm, I measured 54 dBA (quiet) and at 2300 pm, <50 dBA (very quiet).

The base is shows some polishing marks but feels smooth to the touch:

The mounting clips are very secure and easy to use – they snap into the standard P4 retention bracket without much effort.

THE TEST

I tested the Shuttle P4H on an Acorp 4S845A motherboard with a modified P4 1500 to read CPU case temps. I varied fan voltages to get results at 3461 and 2318 rpm.
