Two links for measured effectiveness of CPU fans. Have yet to find any site with fan noise level results. tweakit.com Both P5 and PII fan results cpu-central.com And click on CPU coolers for results sdsmark.com Distributor with good selection of fans AND fan pics/specs. Good for info. Do your own price checking. Networm

Quiet Fans From Anand's BBS anandtech.net Guinea Pig 75 posted 06-02-98 11:51 AM CT (US) If you want a reliable quality fan - look for Papst. These german made fans are reputed to be the best in the world. They are expensive - typically œ20 in the UK - but next time I need to change a fan I think I'll go with one of these. I ought to point out that I have no long-term experience with Papst, but I've seen a few in action - they are extremely quiet. The bearings seem to be good, because even the 6 year-old ones are quiet and still take nearly a minute to spin down!! If you can't warrant the cost of Papst, there are plenty of other brand names that you should consider: Sunon, Adda to name a couple. Just make sure that you do get ball-bearing fans from a reputable manufacturer. If you get a cheap sleeve bearing fan, you can expect it to fail within a year. A friend of mine nearly lost a P166 chip after the cheap fan failed within 2 weeks. bold added

>> URLs for quite CPU fans and quite power supply fans?<< computernerd.com FA6QCB CPU cooler (QC stands for "Quiet/Compact"): Equipped with a 60 mm conventional 12-Volt ball-bearing fan with reduced height of 10 mm. The resultant unit is 15 mm shorter than the FA6EXB ("compact" or at least "compacter") with noise level reduced to 26 dBA (i.e, quite quiet). Airflow is naturally reduced as well, to around the 12 CPM level, giving a thermal performance of 0.65 C/W. Compared with the FAVK6B, the FA6QCB is a little bigger, better in performance and about equal in noise. Both products are high-quality and cost the same. ____________________________________________________________________ The FA80SCB is from AVC (their model EB025B12H rated at 3 Watts) and is designed specifically for exhaust ventilation. Through the use of a thermistor temperature-variable resistor in series with the fan motor, this fan has the lovely chararacteric of being virtually silent at a room temperature of 25 C (77 F) when the motor draws less than 70 mm of current (power output of only about 3/4 Watt), but if it is exhausing case air and the temperature of that air rises to temperatures in the 40-45 C (104-113 F) range, the fan motor speeds up and develops up to 3 Watts of power to really move that hot air out of the case. Of course, it makes a lot more noise when running full blast, but its advantage over the FA80B and all other conventional fans is that it doesn't intrude on your peace and quiet unless it needs to.
