When I found out I was going to be looking at the CoolSonic ICECUBE I naturally took a trip over to their site to have a sniff round the pictures and see what it was all about.

The fact that it appears to be a German product gave the impression, rightly or wrongly, that the engineering standards were like to be high, but there was a niggling doubt in my mind. The ICECUBE looks uncoventional. It's relatively large, it uses the now proven heatpipe technology and it relies on a side-mounted fan for airflow. None of these factors should necessarily impact on performance one way or the other, it's just that so many times in the past I've seen such "inventive" designs fail miserably at their primary function, to cool your CPU.

Selling for a shade over £22.00 including the dreaded VAT over at CCL Computers, the ICEBERG rates as a budget/midange offering, though it looks like it should be more expensive than it is.

So what are the Hamburg based CoolSonic offering us with their ICECUBE cooler? well, this large copper/aluminium hybrid claims a very low 21dBA volume level, all the weight advantages of a part-aluminium construction, all the thermal advantages of heatpipe assisted copper and a class-leading price.

Sound like a tall order? Did to me too! Let's take a flick through the specs.

I'm sure most of you are fimiliar by now with how heatpipes work. This isn't a fictional technology, heatpipes are used in all manner of cooling solutions and can even be found on the latest rash of high-end graphics cards.

The principle is actually quite simple. Liquid at the "hot" end of the heatpipe boils as it absorbs heat and the vapour then moves naturally towards the cooler end of the pipe. As it travels, so it releases its heat and turns back to a liquid again before being drawn back to the hot end again by the capillary action of an internal wick structure whereby it all happens over again.

At 6mm the dual heatpipes in the ICECUBE are actually quite large, but is bigger necessarily better?

Let's take a closer look at the way this thing is put together:
