Hello,
Yes, there are "grooves" on the base, but the surfaces that are there, are pretty flat. Remember: the whole point of this design is to put the heatpipes in direct contact with the CPU -- and the heatpipes are hollow copper. It is probably better that the heatpipes stick up (slightly) above the aluminum backing piece, so they get pressed fully and get good contact.
By lapping this, you might decrease it's effectiveness. Applying the thermal goop takes a different method -- but however you did it, it is working very well indeed.

That's probably because my one line filled up the gap between the center pipe and the mounting plate. But with this much pressure (pins or bolts), any excess would just seep out anyway (and I didn't notice any seeping out after fitting).Ash wrote:ok, its just that when i applied 2 lines on the aluminum bars it spread across the whole cpu evenly.
what are your temps like?
Temps are 32-35C idle, 45-48C load (Q9450 at 3.2GHz, stock vcore).

Some AMD socket observations:
On my unit the groves for the clip is deeper. Like 4mm instead of 2mm like in the pictures I see of it in the review. Tricky to tell if the clip is centered or not. Had to mount it a couple of times to make sure it was fairly centered. Also dont know if my clip was bent or for some other reason the heatsink was repeatedly tilted a couple of degrees when I fastened it.

Any opinions on the new HDT-S1284?
Performance looks great. I remember reading that heat pipes are more efficient with greater temp differential, so direct contact with CPU will make them hotter, thus faster heat transfer to the cool end of the heatsink. Yes?
But the AM2 mounting orientation is a deal-breaker for me.
They have a new model HDT-S1284 with 4 heat pipes with AM2 mounting grooves running in both directions, so maybe this one will mount correctly? Also 4 heat pipes may only benefit the AMD since it's a larger die.
The Sunbeam CR-CCTF (review below) has correct AM2 mounting orientation. Also 4 heat pipes, direct contact, and its performance seems to improve with hotter CPUs

The fan appears to be an ADDA fan, not an Artic Cooling fan.
http://www.addausa.com/model_index.pdf
AD = Adda Brushless DC fan
12 = 120mm frame
12 = 12v
D = Ultra Low (the lowest speed they make)
X = HYPRO Bearing
A = 25mm thickness
7 = 7 blades
B = PWM+FG
GL = Low Noise fan type
This is an outdated list, and doesnt specify our exact fan model, but the weight for all the AD1212 models is the same. 156 grams
http://www.addausa.com/specifications/92-120.pdf
Also im not sure where you got your 600g figure from for the heatsink+fan. The manufacturers website lists 660g
http://www.xigmatek.com/product/air-hdts1283.php
So that would make the weight of the heatsink by itself 500g, i figure the air spoiler and rubber fan mounts is around 4g. Which puts it around 50g higher than the 450g max weight limit specified by intel.
Xigmatek also makes its own Backplate retention bracket if you dont like the pushpings. Here its listed at newegg for $8.49.

OTOH it is perfect for the Antec P180/182 series with top mounted fan.Rebellious wrote:But the AM2 mounting orientation is a deal-breaker for me.
My S1283 is mounted on a AMD 4050e in a Mini P180 with no fan attached to the HS. The top mount 200 Tri-Cool fan running on slow speed is more than enough to exhast the HS.
With the S1283 and no fan attached, my CPU temp at idle is 2 C over ambient room temperature (the mb chipset temp is about 9 C over ambiet room temp). Temps are according to Asus bios.
