140mm fan charts
Today we are going to talk about 140mm fans. Everyday more and more users wish to overclock their CPU’s and that’s where the story begins. With higher clock speed comes greater heat production which has to be dissipated away from CPU as fast as possible. The market is overflowed with fans of many different Brands. Users have such a big pool of choices of performance, air flow, static pressure, build quality or even color. So which fan is better or which should I get for my PC? Well, this question can not be answered that simple. There are quite a few factors which will definitively affect your choice. One of the main factor is for sure your budget, followed with application of the fan. So before you start to search the internet for fans you may answer yourself following questions as first.
1. How much money am I willing to spend on fans?
2. What do I need these fans for? Do I use them for case or radiator cooling?
3. Am I looking for silent, PWM or louder high performance fans?
4. What color will match my build theme? Do I even care for aesthetics?
5. How many fans do I need? Do I need an extra fan controller?

We have collected handful of 140mm fans just to find out differences between static pressure optimized fans, silent fans or industrial grade high performance fans. The 140mm fans have bigger blades so the fan does not have to spin at high RPM in order to bring its proper performance. This means less noise as well as longer lifespan. So, let’s find out.
All tests were performed on a Bench-table with a room ambient temperature of 22- 23°C and if temperature changes we will add delta T °C to the results.
Before testing, we run 10 minutes of Prime95 followed by 30 minutes of idling. This warm up period was done at stock CPU core frequency. For noise testing we are using fanless PSU and we don’t use any graphics card. We do fan noise test over night so we have our room as silent as possible.
Testing system :
We have tested following products with Alphacool NexXxoS ST30 Full Copper 140mm radiator in combination with Alphacool Repack – Single Laing D5 – Dual 5,25 Bay Station and Thermaltake W2 CPU Water Block. The noise level was measured from distance of 30cm, thus we can get more precise values.
For testing we used OCCT software and between each test we left the PC at least 15 minutes to rest so that the temperature went back to the IDLE state. Each test lasted for 15 minutes. The resulting values are the average temperature of all cores. Therefore this results should be considered as indicative only.
We have decided to divide the Conclusion to more categories. As some fans has been developed for delivering of high cooling performance no matter what, others for delivering visual effects or extremely silent operation. We have to keep in mind that we have even used fans which are supposed to be case fans and not really suitable as radiator fans. Many users don’t really care for the last drop of performance and prefer low noise fans. Especially if they use extra big radiators so they can run fans at low RPM.
Most silent fan:
Our favorite fan Antec TrueQuiet 140mm is the most silent fan in this round up. We especially like the rich blue LED and thick silicone pads on fan-frame corners. They offer very low static pressure and low air flow and so not really recommended for radiator cooling. Although, they may be used for radiators with lower FPI density, should you focus on silence only. We picked this fan just to demonstrate, that even case fans could be used for thin radiators. Should you consider to use this combination, keep in mind to use better 240mm rads for one cooled component. Just in case, so you have enough room for heat dissipation. We do not recommend to use this low RPM fans for overclocked systems at all. Frankly, nobody would come to that idea anyway. In order to get decent static pressure, which is most important when it comes to use with radiators, while keep it as silent as possible, we would use either Enermax T.B. APOLLISH or Enermax Everest.
Best cooling performance:
This category is led by Noctua NF-A14 industrialPPC-2000 PWM. The performance is a result of proper development and focus on static pressure as well as focused air flow optimization. The enormous static pressure and high air flow are guarantee that this fans will find its place in server chassis, overclocked or high-end industrial systems. Not only a fibre-glass reinforced polyamide construction, but also water/dust protection make the NF-A14 industrialPPC suitable for rough environments. Noctua even offer 6 years manufacturer’s warranty. Also the overall build quality, frame stability and propeller design is at very high level. The real premium fan. As we expected already this was also the loudest fan in test, but keep in mind that 2000RPM will make some noise.
Optimal performance / noise – the golden way some would say:
This category is led by Bitfenix Spectre Pro 140mm as we have found optimal balance between cooling performance and noise. Although, there are only small differences to other fans actually when it comes to temperatures at high load. Also the Noctua NF-A14 PWM, Phanteks PH-140SP, Silverstone FQ-141 and Thermaltake Riing are delivering very nice results.
So at the end of the day, we can say that you may prefer the fans with higher static pressure as those are suitable for radiator the most. Some users like the silence and color, others like the lighting effects and some care only about highest performance at all costs. We should mention that some of Enermax fans have the option to manually switch the peak RPM.Thus you can control the noise, should you wish to. Other fans had an extra low RPM extension cable included. Also little help against noise are offering fans with anti-vibration pads integrated in frame corners.
