The Frio comes with two 120mm fans, and delivers great cooling whether you use one or both

Akasa's latest cooler is made for overclocking and high-end cooling. Does it deliver?

Cooling your CPU with liquid metal sound like something from Hollywood? Think again.

This cooler is great, but only if you've already got a pair of quiet fans to use with it.

The follow up to the Akasa Nero, the Nero S fancies itself as a premium cooler ready to take on the best. With four fat direct-contact heatpipes and a nifty S-blade fan it certainly looks up to the task. We see if it'll triumph or go up in flames in the bit-tech thermal test rigs.

They might take our lives, but they will never take our Freedom Tower! Well, we'd rather they didn't take either, truth be told - we're rather fond of our lives, and also of this excellent and well priced cooler. Read on to see why (and we promise no more Braveheart references).

We take a look at the X120TF, a weighty copper heatsink and no fan from Korean newcomers CoolAge. It uses an interesting new honeycomb design for its heatsink fins - but unfortunately, it doesn't seem set to displace our current favourite coolers.

The unending drone of your CPU cooler driving you mad? Then perhaps the Gelid Tranquillo can help. With an ultra low-noise PWM fan, but still packing four copper heatpipes and a big stack of cooling fins, check out this terrific low-noise HSF.

The Akasa X4 is a budget HSF that could be next of kin to Arctic Cooling Freezer 7. It sports a nifty version of the push-pin mounting mechanism used by the Intel reference cooler and also supports AMD sockets AM2 and AM3. We see how the sub-£20 X4 performs in overclocked systems.

Could turkey, fir trees and rubbish telly be joined by overclocking this Christmas? That's certainly what Titan is hoping for with its updated xmas edition of the superb Fenrir CPU cooler, rebadged for the festive season. Seriously.
