This would definitiely be an improvement and make the numbers more in line with actual results. Um. I decided not to include cooling as part of the measurement because: 1. Variable quality of HS mounting (775 push-pins etc). 2. IHSs and HS bottoms that aren't flat. 3. variable quality of thermal co...

I would like to actually make RPM the reference control rather than voltage, but the challenge then is to try and get the RPM readings as accurate as possible FelgerC's stroboscopic method is good although labour-intensive, detailed in his "User Reviews" posts. Labor-intensive because I was using o...

Slip Streams have low pressure (small motor=low torque). so that leaves the S-Flex's, correct? "small motor=low torque" is only true for constant power input. It's easy to put more power into a fan hub, so "small hub = low pressure" just ain't so. The SFLex fans are in fact high-pitch (just not as ...

Fin spacing is a little tight... Fin spacing?? Look, the cooling grid is 140mm wide. There are 6ea 6mm heat-pipes that double back, meaning 12 heat-pipes total. The pic reveals that these are side-by side. 12ea 6mm heat-pipes is 72mm total, leaving only 68mm (less than 50%) air space side-to-side, ...

The A-C site has a link to a small PDF spec sheet. On the spec sheet's upper right, there's a photo that reveals some details of why the HSF is only 131mm high with a "120mm" fan. It seems the 120mm fan has had its outer case removed. Such fans are often referred to as "110mm fans" even though the b...

Uses the AC 120mm PWM fan, 1500RPM max. Total height only 131mm for a tower HSF with a 120mm fan! Like the Scythe Mine, it sandwiches the fan between two fin grids. Dimensions 100mm x 130mm x 131mm.

Now reviewed by FrostyTech, showing excellent performance both for cooling and noise. What really interests me is that the HSF can be mounted in any 90 degree direction on an AMD board - something that the Xigmatek 1283 can't do.

XP-120 available here.

An additional consideration is that the HR-01 is about a half-inch taller than the Ninja. I seem to recall the plastic duct is no longer included as standard equipment with the HR-01.

No this is in a regular 3 pin header on the motherboard. I'm wondering if the header isn't supplying 12V to the fan, its almost like the fan is running at 5V. Their is a 4 pin pwm header on the motherboard, 2 actually that I could try and see. Plug your 3-pin fan into one of the two 4-pin mobo head...

Zerotherm is well known as a butterfly HSF maker that uses proprietary fans. It has finally broken that mold; a new 120mm HSF (Zen FZ120) is distinctly non-butterfly and uses standard 120mm fans (1 or 2): see here . edit: The German site Hartware has already reviewed it; results here . edit2: added ...

In the Scandinavian countries, the NCB is available under different marques. Who cares whether a fogbound island or three off the coast of France has them available across the counter?

@Felger Carbon: I'm confused, the results you have seem to contradict Bluefront's results. :? I don't dispute either results, I just want a clear conclusion. The obvious and clear conclusion is that Bluefront and I are independent. We agree on lots of things and disagree on some. Bluefront always u...

So out of those, which would you recommend to be the best 120mm fan for heatsinks with tightly spaced fins? The Yate and GW NCB? And not to thread hijack, but which would you recommend for the Xigmatek HDT-S1283 (AKA Kingwin Revolution)? Personally, I'd use the GW NCB with a U120. I think YL's time...

[...what causes backpressure and how to i fix it? sounds like my nexus would be the best solution save for maybe going down to 800rpm correct?

the SFF21E is the biggest problem. it creates a sort of whistle/buzz when on the thermalright. take the fan off and the noise stops. slow the fan down to around 800rpm and the noise stops... i held my nexus up the the heatsink to see what would happen and the noise wasnt there....wtf? why does it d...

So how does these Slip Stream compare to S-FLEXâ„¢ Series ? :) Slipstreams are cheaper. Slipstreams have a higher pitch, which leads to several properties: ...at the same RPM, the Slipstream pushes more CFM and will in general be noisier for that reason (more whoosh) ...at the same CFM, the Slipstr...

I'm currently using 2x Samsung HD161HJ on raid0. The humming is KILLING ME. It's not even a constant humming sound, it goes up and down. As if it's resonating. Your problem is, you have two HDDs mounted on a common piece of sheet metal. They don't rotate at exactly the same RPM and what you're hear...

I have this one. The price went up since I bought mine; not a surprise with the dollar's sag lately.

Stormtrooper Carbon suggests "could a system be built...", which allows for two or more people to cooperate in building the system!

No-spin fan current draw is highly variable, depending on the fan. Fans that use the simplest, oldest, cheapest drive ICs have no overcurrent protection, and can burn up because the IC is tiny, the same shape factor as cheapo 3-lead plastic transistors (not power transistors). In these ICs, the hub ...

I suppose the bigger the fan the better, since the hub can stay at a similarly small size. However, it also means there is less air-pressure as this is related to the rpms (if I read correctly somewhere around here). For a given fan, the pressure is proportional to the RPM squared. Double the RPM, ...

Here 'ya go: 80mm PWM fan. Comes attached to a heatsink: Here.

Cool master just announced the Z600. Read the Frosty Tech review here . Same cooling and noise as the Scythe Mugen (AMD div); same cooling as the Coolink Silentator but slightly more noise than the much-smaller Silentator. Gee, I wish I could buy a Silentator... :D (Also tested on the Intel platfor...

Terrific review . No noise measurements. Uncritical acceptance of a manufacturer-spec "17dBA". Said to be high priced and very difficult to install. Yep, we all ought to throw away our Ninjas and buy a Coolscraper 3 immediately!

I really don't know if it will work. I am not sure how the signal is sent down the 3rd wire, i.e. if it is pulse/time based, or if it is wattage based. If the signal is simply pulse based, then a simply Y splitter will work. If it is voltage based, well, when you split the wire with a Y splitter, y...

And they claim 12,960 units in stock. By comparison, they list the Samsung 300G HD300LJ at $101.94 with 12 in stock.

Does the above seem reasonable?
