Features & Specifications

The HDT-S1283 packs a full list of features that set it apart from other heatsinks. Aside from being compatible with both Socket 775, Socket 939, and Socket AM2 processors, the HDT-S1283 also sports power-efficient fan and light weight. Let's look at the full feature list below:

• H.D.T. (Heat-pipe direct touch) technology.
• Anti-vibration rubber design.
• Particular spoiler design.
• 3pcs high performance U type heat-pipe.
• Light weight.
• High performance & easy installation.
• 120mm highly efficient PWM fan.
• 3 in 1 application: LGA775 push-pin/K8 & AM2 tool-less clip.

Most of the massive heatsinks I remember from the days of the non-64-bit Athlon were so heavy that they could damage the motherboard unless screwed directly to the motherboard. Thankfully, even with the packaging, I didn't think this heatsink was that heavy.

For those unaware, "PWN" fans are on 50% of the time, and off the other 50%. It's a unique approach to consume less energy, but maintain performance.

These features are made possible through the extensive list of the fan's technical details below.

For reference, Intel recommends a maximum heatsink weight of 435 grams. The HTD-S1283 weighs in about 165 grams over this number. I wonder if it will cling to the heatsink equally? That is, how well it covers the entire CPU without leaning downwards.
