Noctua NC-U6 Chipset Cooler


Test Setup

The test setup chosen for todays review is as follows:

* Intel C2D e6600
* ASUS P5B Deluxe wifi/app
* 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 (F@H) 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.

Test Results

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.

Whilst my CoolerMaster Stacker is a great case as far as maximising positive case ventilation, credit needs to be given to Noctua on producing such a fine performing product. There are several reasons as to why the test reults speaks so clearly in the NC-U6's favour.

* 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.

Looking for a purely passive cooling solution with your chipset cooling? Noctua's NC-U6 chipset cooler dropped by the OC3D Review Labs and we put it through its paces. Check out the review to see what all the hype is about...

Looks damn sweet. Great review as usual Mr Peevles Quote

Thanks mateQuote

Looks really nice, I think the price tag isn`t too bad either. Definately something to consider to replace some of the awful ones mobo manufs put together.

Thing that amazes me is if u look at the item seperately, it looks like it`ll be an awkwardly looking skyscraper of a hs. But when u see it mounted in situ, surrounded by cards etc, u realize it`s more suitable than u might have thought.

Price I seen this @ Performance was about $35 >.< I was thinking it`d be cheaper dollar side.Quote

Mr. Smith
That is a nice little cooler. Quality review too Quote

Nice review. PV, how'd you measure chipset temp on P5B?Quote

14-02-2007, 15:42:50

Nice one PV!

I really enjoyed reading this. Looks like a pretty damn good NB cooler too! Quote

I cant wait till the days when i need a cooler like this, it means I have finally hid away enough money to get an update and the missus has not caught me. Quote

Thanks mate. Temps were taken via Speed Fan 4.32 beta 17 and double checked for consistency using ASUS' own PC Probe.Quote

Hmm. "Chipset" never showed up in PC Probe for me?Quote

PC Probe shows consistently the same temp on my motherboard reading as it does in AI Suite (sytem) and Speedfan. Iirc, the winbond (W83791G) chip for the P5B Deluxe 965 chipset handles the temps from CPU and NB via the die.Quote

They showed in PC Probe for me too Quote
