Noctua NC-U6 Chipset Cooler

The test setup chosen for todays review is as follows:
* Intel C2D e6600
* ASUS P5B Deluxe wifi/app
* ASUS EN8800 GTS
* CoolerMaster 830 Stacker
Prior to receiving the Noctua NC-U6 chipset cooler, I was running the Forcetake Jin Teng active cooler on my Northbridge. The Jin Teng had proven to be an extremely efficient cooler, always keeping my Northbridge temperatures to around the 38 deg C mark. But, bearing in mind it does use a small 40 mm fan to assist with airflow.
In order to keep testing results valid and fair I shall compare the two coolers, but, the Jin Teng loses its active cooling capacity. I have also chosen to not include the standard P5B Deluxe heatpipe cooling solution in the testing as it cools both the Northbridge and VRM's around the Intel 775 socket.
Testing will be conducted entirely from within the case and no additional fans are included, with the exception of what is already inside the case. Idle temperatures will be measured 30 mins after the PC has been switched on, and I will be using Stanford's Folding at Home ([email protected]) client to simulate load temperatures. Three runs will be taken for each chipset cooler and an average taken. Both coolers have been installed using their respective TIM. The ambient air temperature in the OC3D lab at the time of testing is 31 deg Celcius.
All I can say is wow! The results are very impressive and in the favour of the Noctua NC-U6 cooler.
The results get even more interesting when I took the liberty of positioning an 80 mm fan, situated around 150 mm away so that the chipset coolers received additional airflow.
* Due to the smaller footprint in both physical size and height of the Jin Teng cooler, the airflow it receives is greatly reduced by the positioning of the ram slots on the P5B motherboard - a problem that the NC-U6 doesn't experience due to its larger and taller stature;
* The NC-U6 uses dual heatpipes, but the Jin Teng uses one and a reliance on an active cooling fan, and
* The NC-U6's ability to be manipulated up to 120 degrees ensures that it can utilise whatever available air movement comes from within the case. Although the Jin Teng cooler is manoeuverable to some degree, its fiddly installation hardware and reduced range of movement certainly detracted from it's efficiency.
Let's move onto the conclusion page so we can see how the NC-U6 performed as a whole... And whether it's worth your outlay of cash.
