Experience: 90 Days
good quality heatsink and fan
none if on sale
good performing fan,high airflow with low noise and cool red blades

Experience: 1 Months
Worked Without any problem on the first try, worth to buy it so far
For me the price is abit high but well it is the buyers decision to decide wether to buy or not.
I heard that this thing is not that great.but for more i really like it. I think it was what i wanted to be.

Experience: 5 Months
Great fan, moves a lot of air.
I can't find the fan in ncix, but I have the fan not the heat sink and I can say that the fan moves a lot of hair and is really quiet.
It also has orange clear fins with white leds.

Experience: 4 Weeks

It looks great,
It's quiet,
And it cools very well
Fan mount
I love the look, the performance, and the low noise level. If I bought another heat sink it would be the same one. Installation was Ok except for the fan mounting. You can't really install it with the fan in, and adding the fan after the heat sink isn't very easy.
I'm running a Intel Q9550 quad core, default 2.83ghz, and I easily had it stable at 3.6ghz no voltage changes.

Huge heatsink, and cool fan with red LED.
The push-pins for the heatsink are a PITA!! I broke one of them trying when installing it. I am getting bolt-thru from a separate kit.
This HSF could have been flawless if it had the bolt-thru screws instead of the included PITA plastic push-pins. Other than that, its a really nice HSF. CPU is idling at about 26C and the room is warm, so its running pretty cool without OC. Be careful with the HS edges. Also, I had to install the fan AFTER I installed the HS, unlike what the manual mentions.

Experience: 1 Weeks
So far my biggest complaint is its sheer size. I should have read the dimensions before purchase, but I didn't. It doesn't even fit in my current case.

The other issue is the installation, which is a pain with the pushpin system and its sheer size. Attaching the fan was also a pain.

I purchased it at close to full retail, which I'm definitely regretting.

+ Clear lights are different on the fan
+ Decent price
- Pushpin mounting system
- Fins seem a little flimsy
- Attaching the fan to the heatsink
Reviews put this model equivalent to the non-flashy version, plus I was able to get a decent PM, so I went with it. Looks nice in my HAF with the way the clear lights are against the clear-red fan. I purchased the Crossbow mounting kit to make sure it stayed in place.

So far it keeps my Q9400 cool, but haven't stressed it too much to find its limits in my setup.

Cools Great
Fan Mount
HSF mounting system (pushpins)
...I'm very happy with this great cooler, but I was disappointed that, for the price, it had a pushpin mounting system...get the Thermalright bolt-thru kit with this, or the Crosbow kit, and it's damn near perfect!

Experience: 7 Days
Fits my motherboard! Asus P5Q Deluxe
Fiddly fan mount. Rifle bearing fan.
This cooler brought my Q9450 down an average of 12C. You can get a bolt through kit called the "Crossbow" for these and they work very well. This is easy to install, comes well packaged.

The white LED and the red blades on the fan makes gives it an amazingly awesometastic look :p.
Cools decently.
Couldn't get the CPU (e6550) to 3.3ghz on higher than normal V.
So yeah, since I was reading all these reviews about how nicely these HDT HSF cools, so when a friend of mine told me that he wants a better HSF for OC'ing, I got him this. However we couldn't get the processor to 3.3ghz on higer than normal voltage. However, it was probably his RAM, which wasn't the best. (2 ocz platinum 2X1GB sets)

Below are reviews found on other web sites for this product submitted by customers.

Comment: If you are in the market for a high performance heatsink, you could do worse than with the HDT-S1283, it proved itself in our load tests when paired with high speed fans, and was able to keep up with the top of the crop when going in the lower noise regions.

Comment: Overall it is a ok cooler that is very silent but lacks a bit in performance.
Posted by: Zenphic @08/14/08
Comment: In conclusion, I can recommend the Red Scorpion HDT cooler to enthusiast and gamers who don't want to sacrifice looks for performance.
