![]() ![]() So far as cases using 80mm fans go, it's a pretty nice case. It is easier and quicker to actually do it than describe doing it.Ĭlick to expand.They might send you 80mm fan mounts since that's what the case takes, but you can't just get a 120mm fan mount from them (which would be a part for a different case, not an option for your case per se) and install 120mm fan in yours. All of this would preferribly be done with the exhaust side of the fan facing upwards, by rotating the system case or with the fan removed. This is latter detail is not really necessary at all but what i'm writing, it gets thrown in for good measure. If you want to get elaborate doing it, push in on the opposite side of the fan hub so the shaft slides towards the open bearing side till the free play is out of it, THEN while holding it like that, put the drop of lube on it, put the plug back in, THEN release the pressure that held the fan hub inwards and as it slides out, it will pull more lube into the bearingway. A generous drop of lube is put on the base of the shaft, taking care not to get any on the label, nor to touch label sticky-side much with fingers so it remains sticky enough to adhere to the frame still. With plug out, the bearing and fan shaft are clearly visable. ![]() Carefully pull the plug out- taking care not to use a sharp instrument that puts nicks in the area the plug seats into, so it will keep the best air (oil) tight seal possible when sealed up again. Peel back the label and there is (usually) a small rubber plug. ![]() The exhaust side of the fan has the frame extending to the center where it suspends the bearing. Most important is to make an informed choice rather than only seeing a dollar sign. Maybe that's worth $5 cost difference to you, or maybe it's not. If you can't appreciate that the mechanical parts in a PC are among the weakest links, the earlier failure points (unless you're unlucky and happen upon a defective part) then you may end up building a system that unncessarily fails earlier in it's life or requires more frequent maintenance. If this was not obvious to you already, then you have insufficient fan experience to have an informed opinion in the first place. In other words, the end result would be same amount of work, similar noise levels, but lower quality fan. If you want the quietest operation you still have to use a RPM reduction method with these fans, and if you do that, you're making same effort as is needed to reduce the noise of most possible fan options out there. Their low speed fan is naturally going to be quieter than any faster speed fan, and of course when someone (like Nexus or a modder) further lowers it's RPM with a resistor or other control method, that will make it even quieter. A "deal" is not only about what is cheapest, but also how good it is for it's intended purpose.Ģ) If all you can come up with to judge a fan is that somebody reviewed it to be quiet, you are missing the larger picture. Hint- If other fans costing more were no better, only cheap fan manufacturers would still be in business. Yeah, let's be ignorant, ignorance is great. On the other hand, we can classify your attitude as "crapping on information exchange". Blanket labeling something "thread-crapping" is just a wasted effort. We can think of the differing pressures as positive (absolute pressure of the fan) and negative pressure (pressure drop experienced after heat sink/exchanger).1) It would be a disservice to the Anandtech community to only mention "good" things about any product, pretending there are no other product alternatives when there clearly are, or ignoring the difference between alternatives. Because we are looking at utilising higher static pressure fans for possible heat sink or radiator cooling work, the static pressure differential then becomes the difference in air pressure on the inlet and exhaust of the chosen application. Ok so that makes sense so far doesn't it? Essentially static pressure, or more accurately the measure of it, is the difference in pressure. As the pressure differential rises, airflow drops. There is an inverse relationship between airflow and static pressure. It is essentially a measure of the differential air pressure between the air pressures inside an application vs ambient air pressure outside of an application, which for airflow calculation purposes is usually 0 (zero). So what is Static Pressure? Static Pressure is usually stated either in inches of water (inH2O) or in millimeters of water (mmH2O). Furthermore I hope that by covering the basics it will help the newer members grasp what we are trying to achieve a little easier. I thought it would be pertinent to run over some basic theory in relation to static pressure and its benefits, as all fans are not created equal. ![]()
