Hi does anyone have a spare n/s radiator fan for a 944s2.

Three or six blade, lots on eBay

Hi Waylander 6 blades I've only seen one on ebay for £100 for both fans and holder.

Keep looking, the fans are now NLA, so 100 quid and have a spare is a bargain

I'm in the process of making slimline aftermarket ones fit.

I'd be careful of this. On my RST both aftermarket slim SPAL fans flow less than than the OEM single plastic fan. IIRC most OEM fans will flow close to 2700CFM on a single OEM fan. Both of my fans barely break the 2000CFM mark. However, I have little choice in my application as I am running a chargecooler rad in place of where the original fan's space would be.

When only one fan was working it could not cool the car down, but merely slow it down heating up.

I could not find any data on the original fans where did you get the info from? I won't be running AC so I guess I could rig both fans to run simultaneously.

SPAL, Kenlowe and the like tend to provide this information on their websites .

The OEM fans do not appear to have a solid figure against them but figures of around less than 3000CFM per fan do seem to make sense ; their current draw is far more than most aftermarket fans, and as said they do tend to cool down cars quickly ; my 944 used to take about 30 seconds to cool down with the fans on.

Kenlowe do sell fans that flow far more air but of course it is a space game.

On the 944 both fans runs anyway . Both either run at low speed or both go to high speed. If one gets stuck for whatever reason the remaining fan works at full speed, I am guessing as a failsafe.
