Danger Den is a name known throughout the water cooling world for their high quality, high performance CPU water blocks. Over the past few years we’ve seen them churn out more than a few winners for all types of processors.

Today, we’ll take a look at the Danger Den Maze 4 CPU water block for AMD Athlon XP/MP chips. The Maze 4 is the latest in Danger Den’s long standing line of Maze water blocks and they have quite a reputation to live up to.

Specifications from Danger Den website:

• Complete Block Assembled with Top and O-ring
• High Flow 1/2" or 3/8" OD Fittings
• Low flow restriction low pressure drop
• Stainless Steel Hold Down
• Machined Lapped and polished beyond 1200 grit Pressure tested before shipment to 85psi

Take note of the fact that the block comes pre-lapped to beyond 1200 grit! We had heard about the factory lapping of the Danger Den blocks, but it wasn’t until we investigated that we realized that they lapped it pretty much mirror smooth before shipping. The Maze 4 block is a great improvement over the previous Maze 3 block. Not only does it offer a higher flow rate (lower water resistance) but it also cools better, according to Danger Den. *Note – "1/2" or 3/8" OD Fittings" means that it is compatible with 1/2" or 3/8" ID tubing.
