    Heat problem solved - drives on rails

    Over the years I have experienced problems with hard drives on rails (removable trays that slide in and out of the chassis). It could be my imagination, but the problem seems to worsen as capacities go up.

    I've cut the bottom out of the trays, and have experienced no heat-related problems for since then. The hottest areas is and was always the one-inch square chip on the underside of the drive, outlined in red here. I used a pair of wire-cutting pliers to nibble out about three-quarters of the slotted air vents, allowing freer passage of coolling air.

    Re: Heat problem solved - drives on rails

    Hi Chris

    I am probably being over observant here....buuuutt, I was going to just clarify something.

    Looking at the edge of the keyboard on the right of the picture, it looks like it is like one I used on my old 486 about 7 years ago, which says to me, that possibly Chris has got an older PC than he is letting on and he may have upgraded it, hence why he has these removable hard disks on rails which he had upgraded over time by putting in a larger disk or disks. This led me onto think is the chassis that his kit in new or is he using one that is a few years old and does not have efficient fans.

    Tell me if my imagination is running wild or am I making a reasonable deduction <img src=/S/shrug.gif border=0 alt=shrug width=39 height=15>, because it scares the hell out of me that you have taken such drastic action.

    Re: Heat problem solved - drives on rails

    I think it was good of you to share this "techie" workaround, Chris. As some Loungers or searchers might remember, I've been a big proponent of removable drive racks for many years. When I was working at the television network, I had such racks in all 30 - 40 computers that I was responsible for, to enable drive replacement on a rapid basis, using drive master images. Of course, my experiences stopped when I "retired" from that business and were never with drives larger than 80 or 100 gig. Yes, it is true that the heat is unbelievable. I still have a machine here at home with four of those babies in it (80 gig each) and the heat will burn your hands if you're not careful. Unfortunately, the model of rack that I have on hand does not have the slots that yours does, so it would take a little "KTS" work with a saw (or chainsaw <img src=/S/grin.gif border=0 alt=grin width=15 height=15>) to make the cutout that you did. I still have a carton of unused racks out in my garage and that batch all have metal bottom plates, making the workaround a bit more difficult. Certainly worth consideration...

    Edited to add: A picture of the racks I have with the metal bottoms: <post:=343,720>post 343,720</post:>

    Re: Heat problem solved - drives on rails

    Looks like Chris has gone for a walk, Jerry, so I can't resist chiming back in. You DO make a good point about overall case heat and what might be the condition of his case fans, but...

    Sheesh, for an avid KTS guy like you, I'm surprised that you would think his hacksaw workaround was drastic. You should see some of the removable racks that I've installed in the past. We had some "baby" Gateway cases that didn't have room for the racks and my boss and I hacksawed off 2 inch corners on the racks in order to get 'em so they would fit in the external bay of one of those baby-cases. For Chris to cut a hole in the bottom of the tray, exposing the underside of the drive to air circulation doesn't seem so drastic to me. And besides, that's pretty advanced observation of you, from such a small corner of that keyboard graphic. <img src=/S/blush.gif border=0 alt=blush width=15 height=15>

    Re: Heat problem solved - drives on rails

    No don't get me wrong, you are talking to the guy who made a manganel catapult using the CD rom as the release mechanism. Just forgot how strong the catapult was and it snapped the motherboard <img src=/S/flee.gif border=0 alt=flee width=25 height=25> <img src=/S/hiding.gif border=0 alt=hiding width=70 height=24>

    I was just suggesting that Chris's PC may be a few years old (just from my observations of looking at the keyboard) Now remembering WyllyWylly's star post <!post=A Tip for Cooling Your Case,563623>A Tip for Cooling Your Case<!/post> he yanked out intake fan, pinned back cables, moved a few cards around to get a flow of air around the the casing, upgraded the exhaust fan and installed a new hamster. I see nothing of hacking and sawing.

    It appears Mr Greaves has done a stirling job and would not dare argue with him over what he has done, but I would first warn other Loungers that this may be a last resort and try out Mark's offerings in his post before reaching for the snippers and possibly making your cherish HD US 'cos you were over zealous with the snipping...just my observation

    Agreed, but .....

    >possibly making your cherish HD US '
    I'm not touching the HD. In fact, being painfully aware of my surgical talents, I stored the HD in the linen closet until the operation was over.
    This is a hacking job on a plastic case (or "tray"), soft plastic, $15 at Computer Logic House just down the road.
    Cut the thing, vacumn the shreds and shards, back in business.

    heh heh! If you look behind your old kayak in the garage, you'll notice that the old 486 from about 7 years ago is missing (grin)

    You are right. Next time I should choose a narrower field of vision.
    The Big Beige Box is about 7 years old. This keyboard might be the keyboard that came with it. It has (mercifully!) no Windows key.
    I have two or three keyboards on hand, one is always drying out, one is waiting to be soaked in warm detergent, and one is being eaten over as I tripe.
    I don't like this one. When I pound the keys in anger the little ######s pop right out and then I have to spend time learning that the "greater than period" isn't a "caret period", and then I get madder'n a wet hen because of the time wasted putting back keys.

    Kb #2 is out of favour right now on account of the "E", "R" and "S" keys having worn away the ink, which confuses me.

    I put in a new Motherboard about three years ago, but have used rails for about ten years or more now.
    I use rails primarily as backup - slide in, power on, when m/c powers itself off the b/u is done, slide out, power on, return drive to fire-proof safe, if one exists.

    I don't think a custom job on a $15 tray is drastic.
    I still am pondering the contents of the 400GB that I put in last December, which I suspect, failed because of heat problems last June or thereabouts.

    I posted, as Al has acknowledged, to indicate that in some cases (good pun!) modern equipment - in this case hard drives - might be outstripping the ability of the best available chassis to effect cooling.

    I am sure too that the local temperature has a great effect to. This place is not air-conditioned, so the heat gradient between the hard drive (chip) and the air available for cooling is less steep in summer than in spring and autumn. The heat won't be turned on for another few weeks, after which the place will become unbearably hot again until March.

    Now, for extra points,
    (1) What brand of coffee supplied the can lid which is visible in the top of the image?
    (2) Who is the lead artist on the CD whose cover is visible between the can lid and the telephone
    (3) As you probably know, I purchased the telephone from the rummage sale at Bloordale United five years ago for $2. The man who sold it to me, does he sing tenor or bass?
