King of Cable Management
- Apr 28, 2017
Disclaimer: Involves modding the PSU so I would suggest not doing this unless you know exactly what you are doing and the risks involved.
I have noticed that when used in a case without adequate fans, the HDplex GAN can approach 50C skin temperature under normal use, and I measured it up to 65C under extreme conditions with 200w load. So this mod is a direct replacement for the metal top cover of the 250w GAN, with a mesh 3D one + 40mm fan.
It adds 12mm thickness with NF-A4x10 (which is actually 11mm tall) or 11mm thickness with actual 40 x 10mm fan.
- Total of four different fan orientations to maximize compatibility (so it will clear a motherboard edge). The two different 3D models have reversible positioning.
- Press-fit 40mm fan slot design, with push or pull fan orientation, and support for rotating the fan for easier cable management.
- Cable relief area for the fan cable.

(It should look like this)
1) Unplug HDplex & wait 30 mins
2) Unscrew 6 screws for top plate and remove each screw one at a time and put it in a safe place, do not just leave the screws loose.
3) Don't touch anything inside.
4) Replace the top cover with the 3D one.
5) Re install the 6 screws very carefully and straight, not to strip the threads
6) Press in 40mm fan
Test results seem to show that positioning the fan over the right side (DC output side) is more effective:
1) Applying 115w continuous load while the PSU was sitting in open air + very minor ambient ventilation.
The operating temperature was allowed to stabilize at 44C and was reduced to 36C when using "push" fan orientation (and in the "right" orientation).
2) Applying 115w continuous load while the PSU was inside of a 3 liter case with the side panel off and moderate indirect airflow. The operating temperature was allowed to stabilize at 45C after 30 minutes and then the PSU fan was initiated as a push fan (in the less effective "left" orientation) and reduced temperatures by 5C. (Note: ambient temp of intake air = much higher in this test)
