First Impression

Xigmatek's HDT S1284 CPU cooler

Today we are going to look at Xigmatek’s HDT S1284 CPU cooler.   The HDT S1284 is a heat-pipe cooler that consist of 4 – 8mm cooper heat pipes that extend up to aluminum fins.  This cooler is very similar in design to many of the heat-pipe coolers out in the marketplace and would completely blend in if not for Xigmatek’s HDT Technology.  This heat pipe Direct touch technology basically is having the heat pipes them selves touch directly to the CPU core instead of a copper base.  We have seen good results with this technology on other Xigmatek coolers I hope to see good results here as well.

First off lets take a look at how you would receive the S1284 when purchased online or on the shelf at your local brick and mortar store. The packaging that the S1284 comes in is a fairly low key green casing with a window to allow you to see the fan and cooler. There are also various small pics of the cooler and detailed shots that give you the specific features that Xigmatek feels promote the product.  The back side has a basic overview of the specifications as well.

Opening the box you will fine the Xigmatek’s HDT S1284 CPU cooler sandwiched between two pieces of soft foam.   There is a good amount between the outside of the packaging and the cooler itself so there shouldn’t be any concern about damage occurring during shipping.   I found mine to be snug and free from any damage.
