If I got rid of my Thermaltake Spark 7 and replaced it with a Cooler Master Hyper 6 Heatsink Unit will my temps be alot better than they are now on my P4 2.8B. I wanted to get one of those thermaltake silent cat fans (21dba, 52cfm) for it, and a couple more for my case as well so I can reduce the noise level in my computer. Can anyone guess how much cooler it will run with that setup as opposed to my current one?
