To test the NHP-2200 I used a Laser thermal probe mounted between the sink and the chip, as close to the core as I could possibly get without disturbing the mounting.
Firstly I set the voltage for the 650i to its default 1.2v and booted into Windows. Within about 10 minutes the temperature has rocketed up to 70°C and was still rising, so I shut the machine down before any damage occurred. This was extremely disappointing as it showed that the heatsink just couldn't handle the load that the 650i output passively. The airflow in my P180 should have been more than adequate with all the fans on the maximum setting to cool a passive heatsink, but alas, this was not the case with the NHP-2200.
Undeterred, I then sat a Yate Loon 80mm fan over the the heatsink too see how well it would perform with some air flowing directly over it.
Overall I have mixed feelings about the performance of the NHP-2200. It worked extremely well with some direct airflow, but when used passivly it couldn't keep up with the heat-load that the chip created, even with a very high airflow in the case. This leaves me wondering again if Nexus should have designed a fan mount into the heatsink as mentioned before.
