Amazing deal on a top quality fan. 120mm x 38mm. Need incredible performance? This fan has definitely got it. Single ball bearing it would seem, long life powerful motor surrounded by motor coils, 9 fan blades, 11 directional fan blades. 5300 RPM/220 CFM/64.8 DBA. Static pressure is a bit over 21 mmH20. $13.50, whereas a Delta fan of similar quality and performance (link) is around $35.

This will make for a nice new fan on my Megahalems, that's for sure. Remember that it has a 39.6W power rating which is 3.3A. You need a beefy fan controller for this fan. Don't use a motherboard fan header. Power supply or beefy fan controller required.

Would be nice for a CPU cooler though. or mod onto your GPU.

I'd for sure put in on a fan controller and crank it up when I'm benching. 🙂

I got one for my Megahalems. Gonna plug it into my PSU and give it 12v all the time. That's right, nothing but 100% for me. I figured since I'm only going to be using one fan on it (can't fit two with my VRM-G2), I might as well use a powerful fan. I was gonna stick with a single Panaflo U1 120mm x 38mm (2705 RPM/114.7 CFM/45.5 DBA/8 mmH20 static pressure) but then I saw this deal. Too good to pass up!

64 DBA is around as loud as a vacuum cleaner according to here. Although I'm not sure if that would be a huge vacuum cleaner or a handheld one.

I have 2000 RPM S-Flexes except they're branded by Thermalright. They are nice for the price. But I only use them on my case. My heat sinks get crazy fans. My Thermalright Shaman is gonna be paired with a Delta 120mm x 25mm fan... 4000 RPM/150 CFM/56 DBA/12.43 mmH20 pressure. 😀

My Nidec VA450DC finally arrived today.

They figured a fan grill was a necessary safety precaution for such a high RPM fan.

Safety my ass.

Exhaust side of the fan.

First thing is first... look at the connector in the second image. Odd right? That's because it's designed for some server rack I suppose. I had to take it off and solder a 4-pin molex connection to it. I only used the red and black wires and plugged it into a molex chain and into the PSU. So this baby is getting 12v all the time.

Now lets look at some temperature results. I have an Intel Core i5 760 CPU overclocked to 4.2 GHz (1.30625 VCore, 1.375 VTT, so roughly 187W to cool) and a Prolimatech Megahalems CPU cooler. Case airflow is set up as a wind tunnel from front to back, covering the entire motherboard area. Our torture test of the day is 20 passes of IntelBurnTest on Maximum.

First test was done with a Panaflo U1 120mm x 38mm push/pull setup. 2705 RPM/114.7 CFM/45.5 DBA/8 mmH20 static pressure for each fan.

Now the Nidec VA450DC. Specs once again are 5300 RPM/220 CFM/64.8 DBA/~21 mmH20 static pressure. Just one in pull configuration.

Now a graph to make things more clear.

Eyes on the maximum core temps people... near the bottom of the RealTemp monitoring program. You can see that with the Panaflo U1 push/pull setup, max temps are 82/80/75/77 degrees Celsius. With the Nidec VA450DC, max temps are 77/75/70/72 degrees Celsius. So that's a reduction of 5 degrees Celsius on each core. Noise difference? Well my GTX 480 on 100% drowns out the Panaflo U1 push/pull setup. The Nidec VA450DC drowns out everything in the vicinity. If you have a hair dryer at home, go turn it on high. That's essentially what the Nidec VA450DC sounds like. As expected. I'm pleased despite all that racket. $13.50 well spent.

Well that's a nice little temp drop! Especially for $13. I wish I picked one up now. =|

I don't know man. Can you sit next to a hair dryer on full blast while you're on your PC? That's what this fan sounds like. I can tolerate it though. Remember you can't plug it into a motherboard fan header. Most of them can't handle a 39W fan - I believe only a few ASUS motherboards can.

I would hook it up to a fan controller and use it for overclocking. For sure not at 100% 24/7. I like my PC nice and quiet. 😀

Yeah I'm gonna manually undervolt it later or tomorrow and see how it goes. I'll see if I can fit a 25mm shroud in there in attempt to silence the whine it makes.

That must be so annoying! haha Loud as hell.
In my opinion the 5c drop on each core is not worth the noise, but that's my opinion.
I assume your CPU doesn't get temps that high when gaming, and that's what your OCing for? More gaming performance.
So you would probably notice even less difference at normal gaming temps than max load. Not worth the noise once again.
But hey if you like a vacuum in your ear at all times than go ahead, like Jester said.
