With modern hard drives, do you need a fan blowing on them? - Page 3

If the drives are running hot use a small fan (40mm-50mm) blowing in on one side/top/bottom so you have some airflow around the drives. It doesn't take much airflow to keep them cool.

You got 2 hard drives dude, people here are talking about the 4 x 2TB velociraptor enterprise drives and such. You really don't need a fan on them. You should be able to see temps of your HDDs with a program like HWinfo, just a glance at that running for a day and you'll realize your HDDs never go anywhere close to warm.

As long as you got a single exhaust fan or a tower heatsink, you'll have enough airflow throughout your case to keep your HDDs cool. you can use a cigarette to see the flow of air in your case, or just hold it up to the front vent to see it sucked in and the back vent to see it pushing the smoke away. You can also use a piece of paper or toilet paper to the vents on the case, it'll 'stick' if there's air pulling into the case, and it'll push it off if it's pushing air out.

You are assuming case airflow means 5.25 drive bay airflow. Which many or may not be happening.

As has been said many times. Monitor the temps and see. If needed add a fan.

Well that's the thing, I haven't moved them up top yet so I dunno what the temps would be.

As long as you can have good case airflow, and the hard drives just happen to be in the way of the air flow and not in any dead air space then you should be good. if you dont want to add a fan you could always try adding copper heatsinks with thermal tape on them and attaching to your hard drive and hope the case flow will assist in moving needed heat. (thats if you dont want to add another fan because of noise reasons, etc)
post #26 of 26
Try using a positive pressure case fan setup, as the excess intake air will cause air to escape from all the little cracks and especially the big holes, whichwwill force air across your drives and out the case. Try for a 3:2 ratio of intake to exhaust, or even a 2:1.
