Having problems with your IBM ThinkCentre S51 P4 530 HT 3GHz 1GB 40GB 48x CD-ROMS51 8171XX PC Desktop ?

I Have an IBM Thinkcentre 8173-KUB. 3.2ghz, 1.0gb DDR RAM. It is idling at 60 degrees celsius, and gets up around 70 under slight load. I Have cleaned all fans and heatsinks, cleaned off the old thermal paste, re-applied new paste, ensured that the heatsink is seated properly and made sure fans are working properly. I Thought it might be a bad sensor, but then I checked it with a physical digital thermal gauge, which read 60 as well. IBM has informed me that idle temperature is supposed to be


Answers :

This computer and various 8173 are notorious for overheating, blue screening shutting down and or rebooting. The INTAKE Case Fans are of one size and can not be upgraded from factory. The case will not allow for a larger in diameter or depth fan pitch to be installed. The exhaust case fans is the actual power supply. This is a proprietary power supply from IBM. There is not upgrade or exchange for a better functioning power supply. There are two Perhiphial Slots on the case for PCI and one PCI-X slot. You may place a Slot Fan in one or both slots. This will increase the amount of airflow but as soon as any dust and I do mean ANY dust gets on the processor heat sink that does not have a fan this unit will begin to overheat again. What is really needed is a radical modification of the processor heatsink. This model like many S51's do not use fans on the processor heat sink itself. I would consider the addition of a CLP0534 by Thermaltake. This is still in additiona to the $10 Thermaltake A2426 which is needed to still aide in exhausting the air out of the case. This is a $50 upgrade to an older machine that goes for 150 used right now. So either you are in need of a specific application for this machine or just don't want to let it go. In addition to the price tag you must stomach the modifications to the exterior of the computer case to accomodate the processor fan. The existingg processor fan uses a bar clamp lock mount. This must be removed. The bolt pattern will accept a LG 775 proc fan but the case must be drilled through and fitted with bolt holes for allow for the standard mount proc fan. The high tech scenario that may have use in a media center where you will need the slots for a cable adapter interface and can't afford to give up the slot for slot fans would be to use a water cooled system. CL-W0075 is an older system that can still be found some places. This will take all of the processor heat out of the case. This will allow the case fan/power supply fan to be relegated to removing hard drive and motherboard/chipset memory heat only. That brings the modification to around $80.

\015\012Good luck. I have about 5 of these sorry machines. Worked on many of the SFF Thinkcentre's and love them. Just not this one.
Try a stronger fan or you might need a new motherboard
