Because it requires 16.2watts of power and takes about 5 seconds to get to full speed, if you plan on using a rheostat to control it make sure you let it start up at full speed and then decrease the RPMs, otherwise it might not spin up in the first place. As for the noise level - it's painful. It's loud, high pitched, and the air pressure generated when seated on a heatsink doesn't help. My ears were literally hurting after the testing was complete.
Delta 80x25 Low Speed: Worst temperatures out of all the fans (37 idle, 48 load), but it's also the quietest. Delta 80x38 Low Speed: Only 1 degree warmer than the Panaflo fan on load (37 idle, 47 load), but not as annoying. Panaflo 92x25 High Speed: On par with all other 92mm fans tested (36 idle, 44 load), but a bit whiny. Delta 92x25 Low Speed: Almost as quiet as the 80mm low speed with good temperatures (37 idle, 46 load). This is our pick. Delta 92x38 High Speed: Same temperatures as the high speed Panaflo (36 idle, 44 load) and more tolerable. Delta 92x38 Extreme Speed: Best temperatures of all the fans (36 idle, 43 load), but too loud for a desktop environment. As you can see, there isn't that much of a difference across the fans. While idle, there's only a 1C difference between the near silent 80mm Delta and the ear bleeding 92x38mm extreme Delta. On load, there's a 5C difference, but you have to ask yourself: is it worth losing my hearing to shave 5C off load temperatures? More realistically, the 92x25mm low speed Delta is probably the best in this situation. It's quiet and runs only 3C warmer than the extreme Delta (and 2C warmer than the other high speed 92mm models). Another thing to keep in mind is the heatsink being used. Since the XP-90 is primarily aluminum, higher speed fans will have diminishing effects on performance. You can pick one of your choice here. |
