That must of been some bus ride! You do not want to run your Pentium 166 without adaquent cooling, or you will destroy your CPU. Isn't there a heat sink that the fan is attached to ? If it is a conventional heatsink / fan then you should be able to screw the fan on to the heatsink. There are four sheet metal screws on the corners of the fan that screw into the heatsink and hold by compression between the cooling fins. This describes 99 percent of socket seven CPU coolers. However, there is also a < PC Power and Cooling Heatsink /Fan > where the fan is incorporated into the heat sink. http://www.pcpowercooling.com/products/cooling/cpu/cpu_cool/cpucool_1-9_index.htm These were attached to the CPU with thermal double stick tape. The tape is suppose to work like thermal grease but tests show it to perform about as good as no thermal grease. None the less it is adequate for a non over clocked processor and it is easy to install. Superglue wouldn't work because it has no thermal properties and will not hold once it is heated. You could also damage the ceramic housing of the CPU. The only place I know where you could get double sided tape is PC Power and Cooling if that is what this CPU is. But there must be other places. This must be a standard Zif Socket 7 so I would advise you to purchase a new conventional CPU socket seven heat sink and fan ,which will install with a conventual mechanical snap. These can be had for as little as three US dollars. Rode The NOSPIN Group >I have an old P166 machine that was unfortunatley shaken up a bit on a bus >ride.
