The summit stainless flex has been on my 65 for at least 15 years.I also ran one on my Jeep that was daily driver and snow plow.My kid has one on his 360 also.If its quality its as strong as any fan.My 440 runs at 180 all day with an untouched OE rad.As far as that pic of the broken one it ht something and almost amy fan will break if its hitting steel.Ive had one fan break in over 40 years and it was a factory fan.Stay away from the glass fans as they arent as strong as a good stainless one.Rocky
