The SLK-948u is another all-copper heatsink with 40 thin copper fins soldered to the base. Because this one did not come with a fan, and to keep it in line with my other P-4 reviews, I used a Thermaltake Smart Fan II and kept the speed at a steady 3700RPM. It showed up in the ubiquitous brown cardboard box that Thermalright ships all of their heatsinks in. It was nicely packaged, though not as nice as the SP-97, and has the following features:

  • Model: SLK-948u
  • Socket 478 and K-8 application
  • Heatsink dimensions: Top - L95 x W64 x H45 (mm) Fin only, without fan. Base - L67 x W32 (mm). P4 mounting frame - L89 x W38 (mm). K8 adapter installed on P4 mounting frame - L101 x W38 (mm)
  • Machined all-copper base with 40 thin copper fins soldered to it
  • Weight: 635g
  • CPU application: Intel: Pentium-4 socket-478 3.2 GHz and above. AMD: Athlon64 FX 3200+/Athlon64 3200+ and above
  • Bolt-through design with mounting hardware - screws, standoff, plastic clips, plastic protector and Neo plate
  • P-4 mounting clips
  • 2 sets of fan clips for 70, 80 or 92mm fans
  • Syringe of silicone thermal paste
  • Instruction sheet detailing P-4 clip, P-4 bolt-through and K-8 bolt-through installation

Here again is the rather "plain jane" box that Thermalright ships all of it's heatsinks in with the Thermalright name on top and the model number tagged on the side. Inside, a plastic bag and a cardboard holder protect the heatsink. The various parts are to be found below the heatsink and inside the holder. While not as well done as the SP-97, it is still very secure and nothing was damaged in shipping.

Here is the included hardware. As you can see, there is quite a bit of material here, but it all serves a purpose depending on what your application requirements are.

The fan clips that come with the SLK-948u allow you to use a 70, 80 or 92mm fan. That shows a lot of foresight on Thermalrights part. Not everyone has the same fan size, so with this, they've pretty much covered all the bases.

Turning now to the heatsink itself, you can see in the following pictures that it has the V design for the fins which are slotted and soldered onto the good sized copper base.

The base is very well machined and has one of the better finishes that I've seen. Not a total mirror, but very close. It came with a plastic protective cover to help prevent corrosion and to keep out any debris.

Because I have a P-4 system and Thermalright was smart enough to include P-4 mounting clips that use the standard mounting holes, I was able to install the SLK-948u in just a few moments. Briefly, however, I'll cover the high points of doing a bolt-through install. Firstly, you will have to remove the motherboard and also remove the P-4/K-8 bracket. Now line the Neo plate with the bottom of the CPU socket and see which holes you are going to use on the Neo plate. Attach the round-headed screws to the standoffs and push them through the correct holes. Use the plastic clips to hole the standoffs in place on the Neo plate. Place the plastic protective cover over the Neo plate. Now depending on whether you are installing for a P-4 or a K-8, there are a couple of washers that may or may not be needed here. The instruction sheet is very clear and easy to follow, so just RTFM and you'll be right. Apply thermal paste to the CPU and put it in the socket. Place the heatsink into the socket area and attach it to the standoffs with the spring loaded screws, pop in the fan clips, attach the fan of your choice, plug in the fan power and you're ready to put the motherboard back in the case. If you have a P-4 system and you are moving your system around a lot, (LAN parties, what have you) then you will want to definitely use the bolt-through method just to be on the safe side.

Always remember to take your time when doing a bolt-through install, and to follow the instructions precisely. Once attached to the motherboard, it will look something like this.
