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. Otherwise, grab some Yate Loons from Jab Tech, Performance PCs, Petras Tech Shop or wherever you like to buy stuff.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. If you want long lasting fans that will last years, let us know and we can point you to them. While they use a sleeve bearing and tend to die faster, you can not beat $5 each. The Yate Loon suggestion is very good, they are cheap and they are decent quality. While I prefer very high end fans (Panaflo, Delta, etc), there are good alternatives. You can see exactly how the fan will perform with x pressure. ![]() Good fan companies will give extensive and detailed white papers like this one from Delta. It would be like car makers saying that a car will get 40mpg and do 115 mph not at the same time, mind you, but that is how they word it. ![]() Obviously, these numbers don't give a fair representation of what the fan actually runs like. ![]() Another trick they use is run the fan at 12v to get the CFM rating and run the fan at absolutely the lowest voltage it will spin at to get the noise level. Did they measure it at 1 inch? 10 inches? A mile? Around the corner? Through a brick wall? Was the fan in a vaccuum chamber?! Sometimes it makes you wonder when you see these impossible numbers. You don't know how they measured it and they won't tell you. The sound level is usually where it is just disgustingly off. The movement from the air alone is more than 19db, now add motor noise and blade noise.ĬFM ratings are usually fairly correct, although some make me wonder if it had a "tail wind" to help it out or if the numbers were 'estimated'. There are fans out there that claim 90cfm at 19db. Click to expand.Except there are very few companies that actually rate their fans correctly or honestly.
