anybody running electric fans have a source for quality fan control?

[F350camper]

Hey guys. If I could fit a mechanical fan I would, but I cant so I have an electric.

I wondered if any of you IDI guys are running electric fans, and if so, does anybody have a source for quality fan control components?
For a year I ran the little adjustable controller with the probe that goes in the radiator. that crapped out.
Found a fixed setting switch that screws into the head and operates a relay from the aftermarket vett community, it was high dollar, suppose to be high quality. That switch crapped out in a week.
Tonight I just installed another fixed setting switch to drive the relay from speedway motors. It was much cheaper, but as I torqued it down, not gorilla torque or anything, but snug, the plastic cap broke off. I used ABS cement to glue it back on, but no way its going to last, if it even works now.

Anybody have a link to the good ****? I need normally open up to 200° or so, and then back open at 185° or so.

Well, you could geek out and go with like a arduino or trinket to read a standard temp probe. It would be fully software adjustable.

I like omega for temp control stuff.

How about something like this?

I haven't used them but it comes in multiple temperatures. Priced reasonable. Could put a weather pack connector on it.

What type of relay are you driving?

Relay is nothing special, dont remember exactly, but along the lines of a 50a 12v power relay. Thanks for the link, I'll have to poke around there. It's funny to me how much money I have spent on the stupidest thing. I just want something I can install and forget about for several years or forever for that matter

 

[F350camper]

Those look like really good probes Mike, I wonder when they go back open maybe 10° cooler or so?

I pulled the spec sheet and it doesn't give a hysteresis. It's probably pretty tight so there really is no spec for the re-open. Let me dig a little more. I know I have seen adjustable ones.

just for the sake of documenting:

Ran this for a year, I think all the components are still good on it, but some sort of a crack developed in the board and if I flex it just right it works:

Decided to simplify things and spend a bit more money. I found these, and they had a great reputation. I'm thinking what might have killed this is, they may only be rated for 5v ecu signals, and the 200ma-ish 12v to drive the relay I was putting through it killed it:

This one was tonight. Seemed like it was going to work dandy, but after I snugged it down, I lifted the deep well socket off it, and watched that plastic cap fly off.

Here's a couple options.

200 on and 185 off.

Where are you putting the sensor Rob? If you are putting it in the radiator you probably want it to come on a little lower. If you are putting it in the head, I would guess you want it to open about when the thermostat does but that might run it too low. If you are measuring in the head, probably want the fan to kick on just at or slightly over the thermostat and not have a hysteresis like the first one I linked. Probably a little over the thermostat if you have enough fan to catch up. That way the fan will shut off. If you use one of the ones with hysteresis in the head, the fan won't kick off if the off temp is lower than the thermostat.

Im putting it in the head in a port right next to my coolant gauge pickup. I think that first one will work perfectly. I have the fan on a manual switch right now, and I can make that exact scenario happen while just parked. while cruising, it sits at 180° all day long.

 

[laserjock]

Price is right so if it is running too hot or cold you can jump up a level. In a perfect world measuring the radiator water temp would be the ideal situation. As long as it is predictable, no reason you can't go with a block temp. I'd watch it close. There is probably some float in those set points.

i use one of these;

the variable speed type.

I have one of those I am thinking about selling.....

FANTASTIC controller btw.

Electric fans just were not enough to keep my truck cool.

I use this one. http://www.dakotadigital.com/pdf/pac-2700.pdf The first one I bought was defective, but sent it back and got a replacement. Since then (6 months) it has been working flawlessly. It's just a "brain" you still need relays and associated wiring to go with it.

This is the sensor I am running in my swap and so far so good. I put it in the thermostat housing next to the water temp sensor. It kicks on right at 200 deg like stated and runs until it gets down to 185 to 190 range.

I have heard a lot of good from guys who coughed up the money for one of these. They seem to take out the high load when a fan comes on. This initial load is what I believe kills relays in a short amount of time.

Relay kits are all over the place but I don't really think are the best way to control a fan. Right now I am running a Volvo relay set for electric fans but eventually would like to upgrade to one of these controllers.

I've been using these in various applications for my intercooler coolant pump, some fans, some humidification solenoids. They work great. I'd use a relay with them not actually switch the current. I just zip tie them to the the pipe, hose, componet in contact with the "button" and they work fine.
