FAQ:
Q: Is there a problem with a 40mm fan?
A: The problem with fans as small as 40mm is that the fan has to spin fairly quickly in order to provide any decent amount of airflow, and of course with speed comes noise. However, we are now delighted to say that we have a few products which we can thoroughly recommend for any customer who needs to replace a noisy 40mm fan in their PC.
Q: What’s the top speed of a 40mm cooling fan?
A: Big things come in small packages, as the saying goes. Our 40mm cooling fan models prove this point effectively. With models available that have a top speed of over 20,000 rpm, you can generate more airflow with a small diameter fan.
Q: Where do you put the sticker on a 120mm fan?
A: Hold the fan so that the round fan sticker is facing you. You are looking at the rear of the fan. When you plug the fan in, the air will be blowing towards you. If you want a fan to act as an air intake, then the fan sticker will be facing the inside of the case.
Q: Which is the best size for a PC fan?
A: Our most popular fan size is 120mm, followed by 80mm. This isn’t really dictated by customer preference, but more by recent designs of PC cases. As for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm.
