Torin Sifan DDC241 Fan only runs slow when turned on

Never reaches full speed, just ticks over at about 5/10% of capacity. Wiring seems ok (from a novice POV)

Won't start but CPU fan vibrates but will not go full blast. Intermittant


It appears you have a faulty CPU fan and it is causing the CPU to overheat and shut down.
I suggest you replace the CPU fan. remove any dust from the heatsink and put new heatsink compound on the CPU/heatsink.

Why are the fans not coming on in my 1999 deville


99 Deville - have you checked the large fan fuse(s) under and behind the main fuse/relay box ?? (I think this holds for 99 - 2000+ moved the maxi-fuses to the underhood box on the passenger side.)

Also, are your relays on a mount down near the fans ? Some have had trouble with the wiring/sockets there. 2000 or later moved the relays up to the fuse box itself. There are 3 - Fan 1, Fan 2, and a series/parallel (S/P) relay for slow and fast speeds.

Fans run in SLOW at 224 degrees F, FAST at 236 degrees F if there is no air conditioning or DEFROST function set. In the city or heavy traffic the gauge will go to the first tick mark past 12:00 and the fans come on. As the coolant lowers to 213 degrees F the fans turn off and the cycle repeats.

IF you set an air conditioning function, then fans run in SLOW all the time.

If your fans will not run under any conditions, check the large fuses in the underhood fuse/relay box, as well as the small fuses for the fan relays - there are 3 relays: Fan 1, Fan 2, and S/P (series/parallel): the fans are relay set to series operation (voltage drop) for Slow speed, parallel operation (full voltage) for Fast.

I have a Casablanca New orleans fan that I just had fixed by an approved Casablanca repair place. The fan is and always has been connected to a dimmer switch. After a repair of a simple flywheel, the fan...


Hi, is this fan an older fan with the dimmer type control on the fan itself, (and you have a wall speed control in addition to) or is it the later fan with a three speed pull chain control? If the latter, the service rep may have accidentally placed the fan on Medium speed which due to additional capacitance from the speed control board in the switch housing, could cause the symptoms you describe.

Thanks, Brian

P.S. That's an $$$$ fan, glad to see you had it repaired instead of replaced.

Hi i hear a ticking coming from behind the glove box, i tried turning every thing off, it still ticks till i turn the car off


It may be the heater blower fan. It is always on when the car is running. I'm pretty sure the blower is under/behind the glove box.
Does the ticking noise change when you speed-up or slow the fan speed? If so, there may be a leaf or something stuck in the fan blades. You might have to have the blower motor removed to get it cleaned out.
Hope this helps...

If you have played with them the only way is to get it going pretty well is" ....
find the idle screw - usually larger - and turn in 1/2 a turn - hopefully that will keep it running - then find the 'slow' running screw turn it in until it stops then turn out 1 and 1/2 turns. Leave the fast one alone.
Get it started then adjust idle screw so its faaster if need be.,, now slowly turn the 'slow' screw in then out say 1/2 turn and listen for it either speeding up or slowing down leave it at the point where it sounds ok and try giveing a few 1/2 speed rev ups. If it goes back and idles as before - leave it.

The fast screw... (first make sure your exhaust outlet is totally unblocked - the slightest restriction here will cause it to never run right at high speed). Start it up and then try full throttle - same thing as before try adjust the fast screw first in a little then out until it runs well at what seems the faster speed it can - then check that it accelerates well from idle to full speed. If not adjust it a little more until it does.
Once it will idle ok and return to idle and also run full speed, then you can back off the idle screw until it will idle without the chain racing arond the bar.

Bear in mind th chain wil be racing around while you adjust it so keep fingers kids and idiots well away..because you are adjusting it with that chain moving..

Blower fan runs at one speed - very low


There is a sensor on the indoor coil that needs to reach a certain temp before the fan speed will increase. Sounds like the unit is undercharged if the sensor isn't reaching the temp it needs to.

Mercedes 300E 2.8 Liter


Your library may have the diagram. Does any speed work? If it runs on full, there is a resistor pack in the fan housing that can be changed. This unit may also have multiple fuses controlling it. Merc has a habit of building the most difficult cars in the world to trouble shoot. Good luck, sir.

CPU fan races


thanks bigunit12 - as I suspected, no real concern

expect the noise is a pain.

I do think the HS might be marginal and so I shall replace sometime with a higher capacity model, also maybe increase fan flow capacity and add a case hot air extractor fan.

Just to make sure
