That "corrosion" on your CPU HSF heat pipes is oxidized solder. This cooler has three heat pipes formed into a U shape through the fins and base plate. One end of each is a rounded cap formed when the pipe is cast. The other end is crimped and soldered after the pipe has been filled with working flu...

We don't have any updated mounting brackets for this cooler because it's a discontinued item. Our newer models are all compatible with the 1155, including the Ninja 3 cpu cooler (latest Ninja series, redesigned for better cooling efficiency, and better mounting capability). Have you ever thought of...

Three PWM headers is better than average. You can always add more fans using the AC12 PWM daisy-chain feature...

Modern air cooling is water cooling. The heat pipes inside modern heat sinks contain water under low pressure. It's actually more efficient than a water block because the water actually boils at the hot spots. So the difference boils down to (sorry) how a slow fan on a heat-pipe HSF compares to a pu...

It's nice to see 2 cpu headers for push/pull, but maybe let us control both You can run two CPU fans off the CPU1 header by using the daisy-chain feature of the AC12 PWM fan (use another header for the second fan sense line). But why would anyone on SPCR want to do push-pull?! A single slow fan on ...

As stated above Asrock offers decent control (thanks for that information, maybe you could tell exactly which header cannot be controlled by Speedfan?). The Asrock Z68 Extreme4 board has six fan headers. Here are the details: CPU1: 4-pin, PWM fans only (3-pin 12V always), controllable from BIOS or ...

Asrock Z68 Extreme boards have four controllable fan headers (3 from SpeedFan, 4 from BIOS/UEFI). Thanks for the info. How you liking your Asrock z68 btw? It seems like a really good board for the money compared to GB and ASUS offerings. Does have temperature controlled fan settings? I don't have a...

... when running Premiere (rendering a timeline), my system draws an average of 280W, peaking at 340W. Otherwise, yes, burn-in and stability testing are worst case scenarios. When my system is idle, however, it's folding in the background - 8 threads and 512 CUDA cores - it sits drawing 413W. Note ...

I'd love to be able to put a fanless PSU into this build with confidence and with a reasonable amount of headroom for any future possible expansion e.g. an additional SSD or TV card. cmthomson, don't you have a fan blowing directly onto your fanless PSU because it's an Antec P180 case? Has your air...

471W power draw? No way! Some PSU calculator are notorious, I like to use this one . Recommeded wattage for this system:307W (minimum 257W). Xbitlabs measured the power draw for the 2600K both with normal clocks at 114W and overclocked to 4.7GHz at 190W. Even those numbers are way too high, unless ...

Fair enough; it's an okay miniature cooler, but its mounting system is poor. I should perhaps have said "uncompetitive" rather than "junk". Yeah, it's a rather old cooler today and the mounting system has always been Scythes Achilles heel. I've never had to use the crappy push-pins though, the AM2 ...

The CPU you're using uses so little power that the HSF is pretty much irrelevant. The only time you need a heat-pipe HSF is with a CPU that is drawing more (or way more) than 60W at load. BTW, many of the heat sinks in your comparison are junk, especially the Ninja Mini. The best heat pipe HSFs to u...

Another one to look at is the Seasonic X-series 400W (80 Gold). Some people have complained about buzzing, but mine is silent.

Maximus boards have good fan speed support, especially with SpeedFan. In general, modern boards (this one included) expect a PWM CPU fan and will run a 3-pin fan only at full speed (yes you can slow it down with a FanMate, but a PWM fan such as the AC120 is quieter and easier to control from softwar...

A few comments: That CPU heat sink has been discontinued. Take a look at the Megahalems. I like it because it has a very easy and solid mounting system, and also because the fan snaps into the fins nicely. The Nexus PWM fan is very noisy; quite the opposite of its famous quiet 3-pin cousin. Look at ...

Hmm. Apparently some folks making HDDs don't pay attention to history... Some years ago, a very popular 2.5" drive came out with firmware that parked the heads after 20 seconds of inactivity. Seemed like a good idea at the time. But: a widely used OS would update a log file every 30 seconds. Net res...

I have an old P180 with an X-400 supply. I have my HDDs in the bottom chamber with the PS and cool the lot with an undervolted Nexus 3-pin fan at 550 RPM. The power supply barely gets warm, and probably doesn't need a fan at all. But as stated above, I prefer to cool the HDDs, and get PS cooling as ...

Not sure about the 925D, but my 830D was way hotter than any P4. The 9xx series was a die-shrink of the 8xx series, and quite a bit cooler. Just not sure whether the result was more or less than the P4 they replaced. Probably still more, since it was essentially two P4's in a single package.

Wow. You've done a man's job.

But I'm sticking with my Megahalems and selling my Ninja still attached to my old CPU and motherboard and memory...

Any fan can be controlled. I have not seen a motherboard that's able to control a 4-pin PWM fan while unable to control a "normal" 3-pin non-PWM fan. PWM is the cool way to do it, that's all. :) Almost all recent motherboards will not vary the speed of a 3-pin fan plugged into a 4-pin header. A few...

my original ninja uses 2 metal bar arms that plug into the holes, and has 2 ring like objects coming out the metal arms for the ninja's push pin. i don't see why it works for 775 but not for asrock mounting holes Two issues: 1) all 1155 motherboards have a CPU socket back plate and 775 boards did n...

Have you compared the Kama PWM to the Arctic Cooling F12 PWM? I've been using the ACF12 fans for a while, and they are very quiet when new, but seem to get noisier after a year or so. (BTW, I tried a Nexus PWM and it was awful.) So far I haven`t although I`m tempted to try the F12 out. The build in...

by original NInja do you mean ... Model Name:SCNJ-1000 Yep, that one. The original, the classic, the one with backplate & rails on the motherboard and springy clips that were really hard to shove into the rails, the one that had a polished base and solder between the base and the heat pipes. The on...

You didn't mention what motherboard you're using. If it's an ATX board with four DIMM slots, then you're set. I'm using a 2x4GB Vengeance set with a Megahalems, and everything fits; just put the DIMMs in the slot pair farther from the CPU.

I was in the same situation. I concluded that the Ninja backplate would not work on even an Asrock board because of the 1155 backplate and its mounting screws. I almost went with the approach of using some washers with insulating spacers to replace the Ninja backplate, until I realized that the Ninj...

I tried a Nexus PWM and it was very disappointingly loud. The AC is much quieter.

I just bought an X-400 (my old Antec Phantom finally died), and it is completely silent at both idle and load (about 180W). And doesn't even get warm.
