it qwill be barely adequate. I have a 1.0 @ 1.3, and with my FOP32-1, it ran around 60C. I got a SK-6 w/ Delta fan, and its almost never above 42 or so.
I recommend an SK-6, or a CAK38, or maybe even a WBK38 for a 1.4. A 32-1 will work, but you might have some problems. Although, if you have really good airflow in the case and keep the ambient temperature down, it should be "OK" .
