Jetart JAP416A Pentium 4 Heatsink Review
Jetart JAP416A Pentium 4 Heatsink Review
Abstract: Surprisingly, the all aluminum Jetart JAP416A follows in the footsteps of the performance heatsinks and manages to offer very competitive thermal performance statistics indeed.

Jetart JAP416A Heatsink From All Angles

Heatsink Top:
The 25mm thick fan features a seven bladed fan impeller that draws about 3W when running. The fan grill helps to prevent stray wires from being sucked in, and jamming the fan. The fan connects to standard 3-pin fan header on the motherboard, and supports RPM monitoring.

Top: With the fan removed from the heat there are a few things I think you should pay close attention to. The first thing is obviously the multiple cuts in the body of the heatsink itself. Find fins all range in depth, but stay just about 0.5mm thick, spaced 1mm apart pretty consistently. The central portion of the heatsink is solid aluminum, but in the future Jetart may decide to modify the heatsink to include a copper core.

Side A:
The clipping mechanism sits within the fin structure and offers a lot of clipping force while still being pretty easy to use. The side fins can be seen to slope in if you look close enough.

Side B:
In this picture, you can really see how the curved base of each cut actually comes together to form a sort of internal spherical shape within the heatsink. Also note how the heatsink clipping mechanism goes right through the entire heatsink care of two very thin 1mm wide channels. The plenum under the fan measures 4mm tall.

Heatsink Base:

Well, if this isn't the official heatsink of the X-Men I don't know what is. ;-) The useable base area measures just 40mm x 40mm in size, while the entire base surface is on the order of 83mm x 68mm. A side benefit to have exhaust areas at the base of the heatsink is that the warm air can further cool down the processor in most cases. The base surface is very flat, but maintains a sanded finish of about 32 Microinches according to our surface roughness gage.
