Xigmatek Red Scorpion S1283

Hi Guys,

After following quietly , the postings comparing the TRUE & the Xigmatek S1283, I have these questions that I would appreciate being answered.

1. I have a mid tower case with the motherboard mounted vertically. Can I get away with mounting a TRUE or Xigmatek S1283 on a X38 / X48 motherboard without breaking the motherboard?

I can't speak for the TRUE (as I don't have one), but the weight of 600g is really light. I originally had the GeminII which weighs an impressive 847g withOUT the 2x fans vertically mounted without a backplate, and it was fine. I wouldn't recommend hauling it to a weekly LAN party, but it was secure. As long as you use all the appropriate motherboard stand-offs to mount your MB, it'll be fine.

2. Will I or should I install a Backing Plate on the reverse side of the motherboard? If so, could I use the Thermalright LGA775 Bolt Thru Kit?

It certainly doesn't hurt. The TR LGA775 Bolt Thru Kit is totally compatible with the S1283. For an avg street price of $5, it's worth the extra piece-of-mind. (http://www.sidewindercomputers.com/lgbowiscsp.html)

**As a note, it's easier to install the HSF then trying to fit large hands pushing the push-pins. Much easier with a screwdriver. Highly recommended.

3. I have a Sunon KDE1212PMB1-6A (120x120x38)mm fan. Specs are: 108 cf/m @3100 rpm (42 dBA) 6.8W. Would I achieve a better cooling using this fan in place of the original on the Xigmatek S1283?

[strike]The only problem I can forsee is the mounting. The fan you have listed is 38mm thick. The stock fan is 25mm thick. It uses a rubber mounting system via plugs. I'm not certain that it'll work with a fan so thick (but it may stretch that far. The plugs are VERY elastic). [/strike]

****EDIT: Going back, I realize that the mounting plugs do NOT go all the way into the fan, just enough to mount. The 38mm should be fine.

4. Would this Sunon 6.8W rated fan "kill" my motherboard if I plugged the fan directly into the Motherboard CPU Fan Header?

I have no idea. From the 6.8w, and assuming it's a 12v fan, then amperage is .56A I don't know what the maximum watts and amps the fan header on the mb is rated for.

It is interesting comparing the specs of the fan supplied with the HDT version and the Sunon I have at home.

HDT
size = 120x120x25mm
Speed = 1000 - 2200 rpm
Air flow (CFM) = 72.1 ~99.6 CFM
Air Pressure (mmH2O) = 2.6~4.8 mmH2O
Noise Level (dB) = 20~32dBA

Sunon
size = 120x120x38mm
Speed = 3100 rpm
Air flow (CFM) = 108 CFM
Air Pressure (mmH2O) = 7.9 mmH2O
Noise Level (dB) = 42dBA

I show these 2 sets of figures because I want to question the accuracy of the air flow claim of the HDT supplied fan. I think the figures claimed of Air flow (CFM) = 72.1 ~99.6 CFM is high and not what would be achieved in a real life installation.

I am interested in what others think as well.


Thank you for your replies in answer to these questions.

When I first bought the Kingwin RVT-12025 (Xigmatek HDT-1283), I found the 99CFM @ 1500rpm a little hard to beleive as well. I see that they revised the CFM to 56. Much lower than previously stated, and I feel more accurate.

Here's a review I did on the Kingwin RVT-12025 vs the GeminII
