Xigmatek HDT-S1284

Xigmatek has been quick to release several new products lately, all of which are a twist of their popular HDT-S1283 design. Not more than six months ago we tested the Xigmatek Achilles S1284, which was a semi-successful product with four large 8mm copper heat-pipes. Many overclocking enthusiasts were expecting this product to exceed the performance of the original HDT-S1283, however the "Achilles" was not without its flaws - which (ironically) were literally in the heel of the cooler. Xigmatek took notes from Benchmark Reviews and other sources, and has re-released the design under the abbreviated name HDT-S1284 thus dropping the Achilles name. For the sake of clarity, this product has a UPC code of 883371000448. The specifications on the back of the newly-adopted green packaging state that the product name is HDT-S1284 and the product number is CAC-SXHH4-U01.

There are several new standout features that first caught my eye, the first of which is the bare copper heat-pipes which have escaped heat-trapping nickel plating. This is certainly a step in the right direction, at least so far as cooling performance is concerned. Of course, copper is technically porous, and after about ten years or so the highly-evaporative liquid inside will have escaped enough to show signs of degraded cooling performance. For the record, I have been operating a computer company for almost ten years now, and I haven't had a single overclocked system remain in service that long. The other evident change is that Xigmatek has reduced the heat-pipe stagger, so now all four pipes make complete contact with the CPU surface.


Even though Xigmatek offers their CrossBow bolt-through mounting kits (ACK-L7751 fits three-pipe systems, and ACK-L7753 fits four-pipe coolers), they have decided to cut costs and relagate the enthusiast overclockers likely to purchase this product with the stock Intel push-pin retaining system. In our testing however, the Crossbow ACK-L7753 kit was utilized for mounting the HDT-S1284.

Additionally, the HDT-S1284 reverts back to the early HDT-S1283 roots and uses the same black high-output PWM (pulse-width modulation) fan. In many ways, the HDT-S1284 has ditched the Achilles glamour, and stuck to the tried and true basics that made the HDT-S1283 so popular. For this article, the stock fan was tested along side the high-output Yate Loon D12SH-12 fan.
