Xiggy S1283 DK with Noctua P12

[Delavan]

Hi,

I just replaced the fan on my Xigmatek S1283 Dark Knight/w back plate (2000 rpm, 120mm fan) that was getting noisy.
I picked the Noctua P12, for it's ability to create more static pressure than most fans. I'm not impressed, I guess my expectations were too high.

I also think HWC already benchmarked that config in a Xigmatek review back in the day.
The fan is really silent, but i got a raise in temperature!!! A good 3 degrees celsius increase in temps!!!
The Xig is not officially supporting push-pull, so i might have to "tie-down" another 120mm fan (ghetto style).

OR pull the nasty 1 inch thick Panaflo 120mm fan out of the parts bin...OUCH...effective but noisy!!!
I'll try to reseat the HSF, use new MX-2 thermal paste, I'll try the "lips method"

I think AKG got good results with it in reviews...

I'll be moving my config from the Antec 300 to the ATCS840 tomorrow, at least I'll have more room to work with inside...

My question: As my HSF's fan is pushing air horizontally towards the back of the case (I thought it was the only way for HDT coolers) could it be better to mount it blowing upwards?

I too replaced a perfectly good fan with a Noctua only to see the temp come up 1C. That is the last time I bought a poo fan. If you have a fan pushing out the top and rear of the case I do not think it matters which way the HSF points. On some heatsinks there was a little snap on louvre that directed some of the air downwards to help cool mobo components. If you have one of those you may want to take that into consideration when you choose your heatsink orientation.

Thanks for your reply.

The Zig S1283 doesn't have the "downward directed lower fins" like the ACF7 pro for example.
So in this case it doesn't matter.

I just re-applied MX2 in the "double kissing lips" method as described on the above posted review of TIM application.

I jury-rigged a push-pull config with the Poo fan that blows and a Gelid Silent 12 pulling, using tie-downs.
I'm switching everything from the old case to the ATCS840 and Ièll report back on temps after benching.

Thanks again!

I've got an almost identical setup to yours with the stock fan on my 1283, and I'm seeing a maximum CPU temperature of about 76C while folding. Chances are your temperatures were already low enough that changing the fan and adding a second one was unnecessary, but if you're satisfied with it, that's what matters.

Well, the original fan (black+clear LEDs) was getting noisy, that's why I swapped fans.

So your Q9550 hits 76 Degrees celsius? It's a little hot isn't it? I'll report back to let you know how the temps are.

76C is not hot at all.

That darn Gelid silent is not silent... I tried the 3pin header, the 4 pin (this is a PWM after all). Temperatures are worst that with the original fan...
So that push-pull is not conclusive. The poo fan, although getting a lot of press and praise, is NOT pushing a lot of CFMs...

I relocated the Noctua to the rear 120mm exhaust and using a Panaflo 120mm 86 CFM on the HSF...LOUD!
35 db! I get 47-37-40-40 on ilde temps on the Q9550 C1... I don't like that. The MX-2 supposedly has NO curing time to factor-in...True enough it's warmer these days.
