Thermalright HR-05 Northbridge Cooler

Test Results


As stated before for the idle temperatures I ran the PC 30minutes from startup and took the temperature at regular intervals for 30minutes. For the load temperature I ran Orthos on blend stress test for 30 minutes, then took the temperature at regular intervals for a further 30minutes.

This procss was repeated three times, as we do in all of our testing to ensure accuracy.


The results were as follows. Please remember the stock cooler had an 80mm fan blowing directly onto it for the duration of the stock heatsink tests as the RD600 got too hot to have the stock cooler passive. Ambient was 22.7°C

test results

The Thermalright performed 9°C better at idle than the stock cooler and a full 11°C better at load. Also bear in mind several factors:

* The RD600 North Bridge is a very hot chip (stock cooler runs at 65°C idle with no fan)
* The Thermalright HR-05 was a passive solution in the testing
* The North Bridge is right next to a very hot 8800GTX

This makes the results very impressive indeed in my opinion.


I used a SilenX 80mm fan on the cooler and immediately the difference was very good. Ambient a slightly lower 22.3°C for the fan test, so factor this in when comparing.

thermalright cooler with fan

So as you can see the HR-05 performs extremely well with an 80mm Low-dB fan on it. 47°C for this chipset is simply amazing.

Another EXCELLENT review. I was really surprised when I opened the box and saw how big mine was.

I also like how they have 2 versions (straight and offset)

Also like you pointed out it is beautifully made (especially compared to other finned Chipset coolers).Quote
