Quick Look at Contemporary Super-Coolers
In this part of our review we are going to briefly refresh your memory about the today’s testing participants, which all should already know very well by now. We are also going to talk about the peculiarities of these coolers installation onto the LGA1366 platform, since we haven’t talked about it before (because the testbed was not yet available). This is what we will discuss in detail today.
All coolers were tested in random order.
Zalman CNPS9900 LED
We tested the new model from the Korean Zalman Company in the end of 2008 and our impressions were quite ambiguous. On the one hand, Zalman CNPS9900 LED proved more efficient than its predecessor – Zalman CNPS9700 NT, but on the other, it was still losing to the best super-coolers and was selling at a higher price of $89.90.
Anyway, CNPS9900 LED is currently the best CPU cooler from Zalman, so we couldn’t leave it out of our today’s massive test session.
The LGA1366 retention kit is included into the standard accessories bundle that comes with Zalman CNPS9900 LED. This is what it looks like:
There is no backplate in this kit. Instead the retention frame is held with four screws with plastic washers beneath them that are inserted at the back of the PCB:
Since the default socket retention on the LGA1366 mainboards already has a backplate installed, there is no need for a second one.
The cooler is pressed against the CPU with a retention frame with four screws, just like during installation onto LGA775 platforms:
Zalman CNPS9900 LED looks very beautiful inside the system case:
You may have noticed that the plastic shroud covering the fan has been removed according to the recommendations in the manual (which we didn’t notice last time we tested Zalman CNPS9900 LED). Our tests revealed that removing the shroud has exact same effect as covering the slits in it with some sticky tape, namely, the CPU temperature will drop by 2°C. So, it doesn’t matter if you remove the shroud or tape over the slits – the effect will most likely be the same.
