...While Panaflo is cheap, there are consistency of quality issues... Cheap Panaflos mean surplus or reject fans which obviously have quality issues. That's the problem especially in north America with Panaflos. New Panaflos / NMB-MAT (non-surplus, non-reject, from the factory, that do have consist...

The Papst Sintec sleeve bearing really shouldn't be mixed with generic sleeve bearing. It's a passive hydrodynamic bearing, that has much longer lifetime even in higher temps when compared to generic sleeves. OK, it's classified a sleeve bearing, but it's a quality one like Aris pointed out. (the cl...

To address your first point, does it necessarily have to be a long-term solution? Considering how cheap sleeve bearing fans are, and that they are generally quieter than ball bearing fans, many here will opt for a quieter fan that they have to replace more often, rather than a noisier fan with a lo...

Tibors, First off, I was not commenting on your post. (Although I disagree with the reason for the ADDA / Loonie swap on the Seasonics.) If there is a case fan exhausting hot air then naturally a PSU with 120mm doesn't have to exhaust all the hot air alone, and as you say it doesn't "see" the heat g...

dutchman, I personally pretty much agree with you. I will not use anything else than Panaflo/NMB/Papst for "critical cooling", like the PSU. I've made quite a few posts about fan/bearing lifetime here on SPCR. If a person looks up proper data about sleeve bearings instead of reading marketing BS lik...

Running a sleeve bearing horizontally will wear the bearing a bit faster. Papst specifies different L10 specs for their Sintec sleeve (it's called sleeve, but it's really a passive hydrodynamic) bearing when it is run horizontally / vertically. Many generic sleeve bearing fans have L10 figures of ~2...

These fans have been gathered during the two years. If the fans have been just sitting on a shelf the bearings don't like that. Although that will affect some fans / bearings more than others. Measuring them will be difficult (see previous) and just having comments on fans isn't probably worth the w...

One way (OK, this isn't something you can just take from your top drawer) is to use a strobe light. You set it behind the fan and start increasing the frequency. When it seems the fan blades are still, you can count the RPM from the frequency.

It's nice that SPCR has stickies on different subjects. It would be even nicer if people actually read them. Monitor the new fan's RPM. Most likely the PSU fan voltage is temperature controlled. If the new fan runs at full (or high) speed despite having the PSU outside the case then you may need a m...
