I don't think this mobo is designed for significant OCing. Board/chipset temps might go through the roof. Have you looked into it?

It's sort of like a Noctua PWM fan. And the strangely shaped fan blades general a lot more pressure than the Noctuas. If you are using it as PWM, most of the time it will be running at a silent 500rpm. If you need the colling, it has plenty of power to spare. One Apache fan and the Prolimatech will...

Take a look at the Prolimatech coupled with an Akasa Apache PWM fan. It runs something like 500 - 1200 rpms. It is believed to be manufactured in the same plant as the Noctua. I wonder if that's the same plant where they manufactured my wobbly Noctua fan. :shock: Prolima might be the rational choic...

Fans: Noctua NF-S12B FLX 1200rpm 18dBA (x3) Topfan: Scythe SFF21E 1200RPM 20,1dBA. That's odd, why mix case fans? Vertical or horizontal orientation won't affect Noctua's noise character. I'm not sure but the CP-850 may have a history of coil whine, I'd do a google search. Don't understand why el...

Undervolting won't slow down your system.

To silence my notebook's fan noise, I placed it under my TV in an old sony glass door wooden tv stand. My notebook connects to my panasonic plasma via the VGA port and headphone jack. This setup works well for me.

Ok no problem

Have you tried undervolting your cpu with rmclock. It may stop the cpu fan from kicking in.

I assume your bios CPU Q-Fan profile is set to Optimal. Does your mobo's cpu fan temp control need a PWM fan to work properly? Otherwise check all cpu power saving options are enabled, undervolt your cpu, reduce your cpu fan's speed and/or replace it with a quieter SPCR recommended fan. What cpu coo...

If any one else has any suggestions as to how to use a 1156 motherboard with the TNN (fans are not an option) I would welcome their thoughts. You guys may have a genuine reason to keep upgrading your TNN case. But I suspect some TNN owners delude themselves into a belief that their TNN case is the ...

I like it when topic authors include a detailed description of their goals/objectives in the first message body. Subject title is not enough. A competition to do this? I think what we need is a site or a sub-site of SPCR where "passive" pc enthusiasts hang out. All passive info would be consolidated...

What about chipset temps, they're very important in fanless system. Components around the cpu area (VRMs), North/South bridge, etc. I think the mobo is usually the first thing to go due to excessive temp. I'd also suggest standardising the way temps are measured. In my view, a system with a PSU fan ...

I think the chimney idea is a little impractical for me. I'd prefer something like the old Zalman TNN500 case, if I had to go fanless. To bad Zalman ceased development. Otherwise, I'd rather take my chances with higher temps. Silverstone RV01, RV02 & FT02 claim the "stack effect", wonder how these c...

I chose the PWM fans because I've heard they adjust themselves to try maintaining the CPU at a certain temperature. I'm probably running it at 3.8GHz or something so it will be vert much needed. I normally ran my cpu fan at a constant low speed since I don't o/c. But I'm pretty sure my mobo support...

even too close of the right answer nothing for intakes, something above, but not a heater (nothing that use energy)

Are you reducing the temperature around the exhaust vent ?

Are you increasing the height/distance that the air inside the case needs to travel to exit outside the case ?

My guess to maximise case cooling and convection. All intake vents at the bottom and all exhaust vents at the top. Heat sources towards the top and stacked horizontally. Streamlined internals to minimise the occurence of any hot air pockets. Raising the heat source(s) temperature will also aid conve...

I hope that they will be very quiet with the ULNA's. I've never tried a NF-P12, but it should be very quiet at low speeds (~600). Use the lowest speed adapter and mobo fan control to further reduce speed. Undervolting your CPU will also help reduce load noise/temps. Look out for manufacturing defec...

I'm running all the fans at 5 V. Looks like the NF-P12 is already undervolted, so adapters may not help/work. Removing the case fan and placing it on the cpu cooler may help to reduce noise and improve cpu cooling. I'd also use mobo fan control to further reduce speed/noise. Here's Noctua fans nois...

NF-P12 is not supplied with speed adapters because it was specifically developed for CPU coolers and would be speed adjusted via mobo fan control. The NF-P12's I just got from Newegg came with 2 adapters, including ULNA. They are listed in the product description. Am I missing something here, or di...

NF-P12 is specifically developed for CPU coolers.

The 120mm at the back is the NF-P12, that is, Noctuas top model with the "vortex-control notches". This is the one making the most noise actually, a sort of rounded, yet sharp tone. Of course, all this is relative, but this is SPCR, and one can not make compromises when it comes to noise! The thing...

Reducing the need for active cooling is green.

Nice find thanks. But I totally missed this one.

You may wish to re-post with something like,

"Reviewed - NH-D14 vs IFX-14 vs Triton 88 vs Prolimatech"

as the subject.

As an ex 500A owner myself, I understand your concern. However, with careful component selection, a fan based system can be virtually inaudible when positioned under a desk. For example, A very quiet fan based system with an SSD, can be at least as quiet as a 500AF system with one quiet desktop hard...

Unless you're a absolute silent PC noise freak. I can't think of a single rational reason for you to upgrade your 500. Your decision. Sounds like you'll need help upgrading. Ask the guys at Endpcnoise.com if they'll do it for you. They're the only guys I'd trust to upgrade a 500. I suggest doing a f...
