- Retail package
The retail package of Spire Fourier Noctua SP602B3 is big enough to make you wonder what exactly is placed inside at the box.
Opening the box unveils just the various installation bases for all kinds of cpu processors :)
Getting familiar with the Spire fourier cooler, we can see a massive 120mm rotating fan at the top
While there are four full copper heatpipes coming from the base to the aluminum fins
The base is made out of full copper with excellent finish..
- Installation
While in the beginning we tried to get everything together, something didn't work exactly as we hoped. The design of the cooler itself does not allow for an easy installation for two main reasons. The pre-assembled mounting screws are very hard to be rotated without the included tool. That means it takes much time to rotate the screws and if your motherboard has a big cooling system, then you are out of luck.
The second reason is that the design of the heatpipes will mostly interfere with the existing motherboard cooling system in a way that you will need to apply extra pressure to get everything together.
The following pictures illustrate the mounting problem we had with this cpu cooler:
We had to apply force in order to get the Spire Fourier base to conact the processor. No matter if we rotated the cpu cooler, the problems remained the same:
After several attempts, we got everything installed, even we weren't very sure about the performance of the cpu cooler since the base was not firmly attached on the cpu.
