Asetek Chipset Waterblock

Chipset Waterblock Test – Joe

SUMMARY: OK choice for chipset cooling, although pressure drop may be a problem.


The good guys at Asetek were nice enough to send a Chipset Waterblock to test out.

Asetek’s Chipset Waterblock features

  • 10mm/½” push-on fittings
  • 3/8″ thick acrylic top
  • finger screw mounting
  • Copper base

The base of the quick connect fittings used in the system are a bit smaller than the 3/8″ ID of the tubing – they measure 9/32″ at the widest point:

Nip Base

The base


appears well machined – I could feel no ridges.


The Asetek Chipset Waterblock was tested using the CPU Die Simulator and Waterblock Test Rig.


Test Conditions: Inlet Water Temp: 28.5 C; Mounting force: 15 pounds; Heat Load: 70 Watts.



Pressure Drop – psi

Pressure Drop – inches H2O

NOTE: These results are NOT comparable to tests done by others.
Unrounded data: 0.187 C/W with 0.0014 std dev.

Test Results indicate that the Asetek’s pressure drop (or head loss) across the waterblock is moderate; flow resistance at this level means that it should daisy-chained with a low pressure drop CPU waterblock. Decreasing waterflow to 0.5 gpm increases die temps by about 2.5º C, while increasing flow to 1.5 gpm decreases die temps by 1.6º C.

For a comparison of the Asetek’s performance to other chipset waterblocks tested to date, see Waterblock Test Results.


Asetek’s Chipset Waterblock is an OK choice for chipset cooling, although its pressure drop could be a problem daisy chained with a high pressure drop CPU waterblock; at a minimum, adding chipset and GPU waterblocks will require a larger waterpump to extract top performance.

Thanks again to Asetek for sending this our way.
