Hi Tom, my first question on your site tho' I've lurked many years.Ihave a question about processors and cooling. Today, my daughter took delivery of a "smartphone" boasting a 3 core proccessor. This device is as as thin as my wallet on payday -1, and cooler than the ex's passion even a good day. Now, I am writing this letter on my worakday machine, which I have tried to make as quiet as possible, eg by installing ssd drives,rewiring my home with Cat5E cabling, and and banishing all regular "spinning" hard drives to NAS in another room. All OK. bar the fan! My workday machine also boasts a 3 core proccessor, but needs a cooing fan the size of a house brick. Why is this Tom?
