Cooling Issue With Electric Fans

I recently put in a fresh SBC 350 along with a Champion 3 row aluminum radiator. Ran the mechanical fan for a month and it was always a cool 190 degrees. Well yesterday I installed a dual 12" electric system (puller fans) with shroud and I noticed the temp climb to around 230 before I shut her off (the fans were on). I don't like that at all.. Each fan show to pull 870 cfm for a total of 1940 cfm which I'm not sure is enough for my set up.

Anyone have any insight as to what I should do.. Or should I just stick to my good ol reliable mechanical fan?

Thanks!

Was this moving or stopped?

Here's a couple pics of the setup. Temps got up when I was driving around.

I'm sure you have checked for fan rotation, but I do have to ask.

Opps sorry, noticed you had said pullers...

Absolutely. Fans were both running.

I have to ask, why did you choose to go electric when the mechanical was working perfectly?

Good question. HP increase, efficiency, etc. Plus I had it laying around for awhile so decided to give it a shot...

If it ain't broke.....

I must say, that's one good looking engine compartment.

Sorry I couldn't be more help. Good luck, and let us know what you figure out.

I had dual 10inch on my 360 and always battled heat. New rad, flush, test at replace etc. I then put a co tour fan in mine a d it worked a lot better. Lately I have wired it so the low speed stays on all the time and it is working really well. Ever had the option of going mechanical.

X2 I've had great luck with my Contour/Mystique fan setup and it's been working great on my 360 for two years now. I did some other cooling mods but that had the greatest impact.

The parts shop that stocks part for Skylab II will not have parts for our year/model of Jeep
We cannot accurately judge the trajectory of a speeding critter (cat, dog, sasquatch)
Record heat waves and floods only occur when we visit that area

Upon further review, I put back on my mechanical fan and the gauge still reads high. So now I think it might be my temp gauge.. In the electric fan kit they included a new sending unit. So I removed the original one that came with my gauge and did this (see pic). Appears now to be reading high. What else could I have done since now I have 2 wires that need to be hooked to my sending unit?

I'd probably try using the original temp sender with both wires attached, and see if the gauge reads accurately and the fans still work properly.

The problem I had with that was the original (aftermarket) sending unit did not have a place to mount another wire. The wire went all the way down inside the brass part which screwed into the engine block.
