[601HP]

jeff.nel,

I've had the Cobra 14 years. During the first 3 or 4 years I experienced the same temperature spiking you described because I just had the 2 pusher fans in front of the radiator. As stand-alone units they are less than adequate for me in stop and go driving. Once the temp reached 200 degrees, it began ratcheting to higher readings faster than I was comfortable with.

I eventually mounted a 16" Spal puller fan behind the radiator. My temperature concerns vanished with this installation.

My choice was the Spal fan. Other brand rear-mounted pulling fans will certainly work well to overcome the limitation of the front-mounted fans.
