Xigmatek HDT-S1283 or Xigmatek S1284 "Achilles"

Post by axee » Sun Feb 08, 2009 8:36 am

Hi!

Unfortunately in our country (Slovenia) HR-01 + is not available, so I am looking at those two heatsinks. I'll put Scythe slipstream 800rpm on heatsink (so included fan is not important). I wonder which would perform better with such low airflow (p182, two slipstream 800rpm as case fans)? By the pictures, I have feeling that Achilles have bigger space between fins, or I am wrong?

Thanks for advices!



PS: sorry for my english :D


Edit: I forgot to mention: I have zalman cnps9500 now, the fan is on 3v (950rpm) and temperatures of processor (pentium d 830 @ 3.8 ) are 40 idle and 70 full load.

Frostytech has reviews of both. To quote their reviews, for the s1283, "The aluminum fins measure 0.35mm thick and are spaced 1.75mm apart." As for the s1284, "Each aluminum fin measures 0.4mm thick and is spaced 2mm apart from the next."

Hi axee!

From what I can tell, the S1283 has ample spacing between the fins. MikeC made note of it in his review of that heatsink.

The Achilles looks nice, but it doesn't perform as well as the S1283 in most reviews. Many note that this is probably because not all four of its heatpipes make full contact with the processor. The S1283 performs better on dual core processors, so in my opinion it would be better for your purposes. The Slipstream will provide ample pressure either way. The temperature variation between the two is usually only a degree or two, so you'll be fine with whichever heatsink you choose. Personally, I would take the S1283, because it's cheaper and performs better on smaller CPU dies; I'm sure that the Achilles would also perform admirably, should you choose to go that direction instead.

Hi,

I think the HDT-S1283 is the better design, in terms of the base: the three heat pipes all make contact with the CPU, which nearly covers all three. With four heatpipes, the center two get most of the heat, and the outer two barely touch the edges of the CPU, so they really don't do much.

Check the older threads on this, on SPCR; that also show the best way to apply thermal goop to this heatsink.

Thank you for your help!

I am planning to buy some intel q9xxx series in future (maby 6 months), what would be the best future proof heatsink for quad core processors?

s1283 is more than enough for any x86 processor ever made!!!

and s1283 is also the highest performance for the lowest cost AND lowest WEIGHT! it uses less materials than other heatsinks and cools as well as the other best heatsinks.

I'd still stick with the S1283. It's going to serve you well, no matter what. It might even be MORE effective on a quad core...I'm not really sure.

Bottom line: get the HDT-S1283.

I steel feel bad because I have feeling that hr-01+ is so much better, in spcr tests is much better than S1283 on low airflow. Is slip stream 800rpm airflow really "low", or it compares with nexus on 7-9V ?

The HR-01 Plus is a better HS, but not a lot better. A Nexus is 1,000RPM, so 7-9v is roughly the same as a SlipStream 800RPM at 12volts.

After reading both reviews (again) I realized that there aren't no differences between these two heatsinks at 800rpm (spcr recomended fans), HR-01+ is better only with 500-600rpm fans.

Am I maby wrong? :D

Another question: what would be the perfect fan for S1283, with max. 800rpm?

Hi,

I would suggest the Scythe Slipstream 800RPM. Or you could try a duct, or it may work well enough to just be "passive", if your case has adequate air flow.

I run passive on my amd 4850e with the s-1284. should be fine for 1283 too. i don't think there's much difference between 1283 and 1284. i got 1284 because the price was the same as 1283.
