I have been using one on my Mark VIII fan for two years with no issues at all! It's a great little device, too bad they went out of business.wesb said:What do you think of yours I have purchased one from a fellow I know. IS it a good investmeant?
BP - I just bought that Hayden controller from Autozone. That prob is a little odd looking. I wanted to ask you, did you have 2-12" Hayden fans on your car. Did they fit your radiator? I want to go with the dual fans because I think they look cooler then just one but dont know how wide my 3 core GDI is. Anyone?BP Convt said:I had a PMS vari flow controller on my car for 2 years and loved it. Especially after buying two of the Pep Boys variety fan controllers that lasted less than 2 weeks. Disadvantage, my dual 12" inch fans made an objectional high pitch whine when not at full voltage from PMS controller. Disadvantage, I paid over $100 bucks for mine, but was worth the expense from a reliability standpoint. I've also had really good luck with the fan controller that came with my dual 12" elec. fans from Hayden (purchased from Summit Racing). The Hayden controller just looks ugly as heck since the controller box is large for an electronic piece and uses a sensing probe that goes into the radiator upper inlet hose.
