Quiet a Shuttle SB752G2?
Take a look at the back of this Shuttle PC...
http://images.sudhian.com/review/sff.../Figure_4a.jpg .... If the grill/case was cut away from where the fan blows out, wouldn't that make a BIG difference to cooling and quieting the computer? |

Yes, that will help a LOT, but there are some other considerations that go along with the idea. If you were to reduce the fan RPM so air movement remains constant, you'd reduce noise but not cooling to any major extent, but that would better preserve the present airflow design. The more air you move out that fan (hole), the less you'll be moving through the power supply, which may be as likely to fail from heat as the rest of the system. I would expect significantly less air though the power supply if you cut that out. Those power supplies with tiny fans don't move a lot of air to begin with so it's good to preserve as much of that airflow as possible. I'm not suggesting that you not modify it, but to also look at ways to increase airflow efficiency though the power supply. Cutting out the power supply's rear grill may not be enough, you might need to alter it's intake, but again taking care to keep the airflow pattern similar, not diverting air away from the path it was designed to follow. With all of the above, futher gains will be see from increasing air intake passageways, but again looking at where, how it affects airflow distribution. Airflow over the motherboard's power regulation region should not be reduced, nor around the hard drive. Dave |

This particular Shuttle has screening on each side of the case to allow airflow in, so I don't think there will be a problem getting the air in. There's a picture (not the best) at: http://images.sudhian.com/review/sff...2/Figure_7.jpg The PSU acutally has two 40mm fans pulling air through. I doubt that they move much air. I will probably end up trying to mount a fan on the side the case sucking cool are into the PSU. Thanks for the feedback. Looks like this is the way I'm going to go. |

I installed an AIW 9800 Pro graphics card in an SB75G2 and blew the
standard power supply after about a month to six weeks. I replaced the power supply with an external power supply (ThermalTake 480W pn W0010) and ran the lines into the case through the former internal power supply's connector location. So far, so good after a week. Using Aida32 to check temps, the CPU gets up to about 47 C when running a DVD (Plextor 504A drive). Nothing else but a hard drive and floppy installed. Nothing in the PCI slot. |
