By the way, every time I see you on this forum I click on the link in your Sig too see where it goes. Are you ever going to change that?

No, I really only use it for email at the moment. If I have a need for a portfolio again I will dig out the backups and knock something together, but you really only need that if you are wanting to work for someone else which I dont really want to do again.

fair enough

timmmay: I have two front fans to keep my hard drive cool, one rear to pull the heat out of the machine. I found the fans that came with the cooler master silencio case were very low powered, I replaced them and things got cooler.

I can't remember where, but I read a study between drive brands and temperatures (graphs and all) which indicated that drives operating over 40'ish degrees failed a lot more than drives operating at cooler temperatures between 27 and 35 degrees or somewhere around there. It was common amongst many brands but others performed better temperature wise.

This is going to bug me all week and I'm going to waste hours trying to find at 3AM now instead of sleeping.

I suspect I trust the Google data. Also look at the SMART data analysis from BackBlaze, they have a report too.

The main reason that I prefer front fans is that I can then put several PCs side by side on a shelf or under a desk and they pull cold air in from the front. If you have side intake fans, you start having to leave gaps between the cases and that wastes space.

you want to have more exhaust than intake so i normally just use large cfm for the rear and top if available it will draw enough air through the front to keep it cool.
My current has a 140 rear at 80% to stop the whine + psu fan drawing air from the bottom below the graphics card and its plenty enough for this setup i don't overclock either as i don't see the benefit.

Airflow depends on what motherboard type you have installed and the version of the type it is (ATX is up to v2.4 now I think). The standards specify which direction air should flow which fans should be pulling into the case and which should be exhausting it out, lots of info all over the iterweb about it.

Sometimes just jamming in fans makes things worse if you end up creating low pressure areas where there should be good air flow for cooling.
