Second Fan: BDCW vs AdvMachines

mixermsk · 01-12-2013, 12:32 PM

I want to install a second fan on my 990 Adv. On the internet I found the options from two manufacturers: BDCW and AdvMachines. Is there a any significant differences?

Thanks

Here is what else you could use. I just got a Spal 5.2 pull fan off ebay for $ 50 and installed it. The New Spal fan is the same size as the stock fan on the left side. Its a perfect fit. I like the fan better more air flow then the other two fans plus cheaper. Here is a link of my fan set up.

I have the BDCW aux fan. Easy install. She works like a charm.

whichever route you go opt for the lower temperature-actuated fan switch (goes into right hand side of radiator)

this helps keep the temps down for sure- fan comes on sooner, but doesn't stay on long as it the engine/cooling system has accumulated less heat to shed. Without the sensor change both fans will run but run much longer, which (assuming you are riding slow/offroad which is where the additional cooling is REALLY needed) will be hard on your battery as the alternator isn't spinning fast enough to keep the voltage up.

I used Ken's AdvMachines kit as that's all there was at the time- and while saving a few bucks is always nice I'd rather give my $ to ADVRider-supporters (both BDCW & AdvMachines) and not somebody out of the loop.

I found replacing the stock temp switch didn't allow the radiator and thermostat to do their jobs, and the fans actually ran longer than when I switch back to stock.

Love the 2 fans though.

They would run longer/sooner since the switch is set at a lower temperature then stock. This is a good thing.

I went BDCW as it came with all wiring and bracketry.

If you're a bit more hands on, the SPAL and cable ties is also a winner.

I'm not sure why running longer or sooner is a good thing.

If the radiator isn't being given a chance to do its job then I'm just using the fans to do the same work. When given the chance to do its job then the fans runs less frequently and shorter than they used to.

Where the single fan ran for ages sitting in traffic, even on very cool days, the double fans run for a fraction of the time. Since coming back from CJs tech weekend the bars haven't gone to more than 5, even once.

Question for you guys that have installed a second fan: What did you do, if anything, about installing a shroud similar to the left side fan?

I just installed my ADVmachines fan and still have the tanks, etc off. I'm wondering if I need to install some sort of shroud to direct the hot air away from the right tank.

I'm very impressed with the bracket and electrical connectors that came with the ADV fan. The installation could not have been easier (with both tanks off).

I used some quarter inch thick adhesive backed heat shield material I purchased online. So far so good.

I used the ADVMachines kit simply because I did not know BDCW had one at the time. I wouldn't hesitate to use either.

I did nearly 18,000 miles around the country this last summer and had a couple of overheating issues when running slow on trails. Never had a problem running down the freeway, even in 116* heat.

So to cure the slow running overheat issue, I rode faster

...unfortunately that created other issues so I installed the second fan a and lower thermostat.

Haven't had another over heating issue.
