While waiting to pass Canadian Customs - Coming back from Camp928 this week-end, I heard my radiator fan spinning at full speed. At home, I saw that only one was running (passenger side).

I checked the fuse and it was blowed. This is the second time that this happen - same thing last fall after Frenzy.

I saw the a new fan from Porsche is around 325$ (928.624.145.00)

Is it possible to rebuilt those fan?

Anyone tried those : http://www.v12s.com/porsche_cooling/porsche_928_cooling

Other options?

Switch the connectors to the fans first (with fuses in place), and see what occurs. It may not be the fan. Could be the final stage amplifier.

If the fan does need replaced consider buying a new aluminum housing and Spal fan set from Hans SerVaas here on the forum. If memory serves his kit isn't much more than the price of one fan from Porsche.

+1 Hans has designed and built a fan set and cowling that is an immediate upgrade from OEM. More CFM and 1 minute removal after installation which takes about 30 minutes total. A great product.
No affiliation except for a satisfied customer.

I assume Hans' set up would work for S3's as well? Just curious.

+1.
If you want to test with mine, or test yours on my care, just let me know.

The original fan lasted how long? 30 years? Through how many cooling cycles? Thousands?

Note that your car did not overheat when the fan quit. The other fan simply ran at a higher speed, which you mentally noted and checked when it was convenient (not sitting on the side of the road with a boiling engine.....or worse.)

The 928 cooling system is one of the things that makes the 928 such a remarkable vehicle. The electronics and logic circuits, combined with the two fans that can run at different speeds (when required) make overheating a virtual non-event. Re-inventing or re-engineering something for an incredibly functional and reliable system makes absolutely zero logical sense.

Do yourself a favor....order two new stock fans and install them as a pair. Make sure the amplifier works properly on both high and low speeds, when you install the new fans. Make sure all the inputs to the logic controller work and that the logic controller sends the proper signals to the amplifier.

Done.

I have an extra fan from my '94 GTS ... PM if interested ...

Of course, some 928s do not have very sophisticated cooling fan systems with logic and variable speeds.

As a datapoint, the Hans fans can/do fit S3. I added a couple of mounting slots to clear some tabs on my lower core support, but it is basically bolt in.
