Hard-drive ventilation in Antec SLK1650 case?

M

Matt

The Antec SLK1650 and SLK1650B look like very good cases:

http://www.newegg.com/app/ViewProductDesc.asp?description=11-129-150&depa=1

and I see they are available for around $60 shipped from techonweb.com
and elsewhere.

_Below_ the hard-drive cage there is a good vent and a holder for an
80mm fan, but I can't find a picture that looks _through_ the drive cage
at the front wall---to see the direct ventilation available to the hard
drives.

Can somebody describe the hard-drive vent, maybe by comparing it to the
rear 120mm vent? What are its approximate dimensions? Are the holes
about the same size as those of the rear vent?

TIA

Also what is your general experience with the case?

I had a similar case by Antec. They have a series of cases that look
the same - same size and style except some have fancier options , the
thing you notice is some have swinging panels that hide the drives and
some dont. Thats the one I didnt like. It was actually slightly
smaller than the avg mid tower I was used to buying - Enlights,
Supermicro etc. It was actually slight weird in that it was in the mid
tower category but an inch or so less taller. yet it was wider so it
left room inbetween the side panels and drives.I was already thinking
the mid towers were fine but a full tower was really roomy , that
slight difference in height made it feel cramp for me and the width
increase though theoretically you could say it increased air flow -
still made it feel surprisingly cramped inside. I hated it in fact
that I got rid of it for half the price I paid for it a few months
later and bought the full tower Antec. Ive been totally happy with it
ever since. I just dont notice any feeling of being cramped inside and
heat building up.

Thats not to say the case stinks. It really depends on your needs and
Ive always tended to use boards with an extra IDE controller and max
out my IDE devices so I had 4 or more flat grey ribbon cables tangled
up in a nightmare with power cables. I would guess for people not
using that many devices its not as much of a problem.. You could
argue that nowadays with SATA and you could get round ribbon cables
too - even someone who was using the max amount of devices would be
better off than I was.


Also I didnt notice whether there were any ventilation holes in front
of the 3.5 cage but the full tower antec I have has two removable
3.5 cages that are designed to hold a plastic square bracket in which
you can put an 80mm fan in front of the cage blowing air over the HDs
or whatever you put in it. The full tower also has TWO holes in back
below the PS fan outlet as well as the usual one in front at the
bottom. Also often comes with a side panel with a fan hole.

You can find lots of variations on the Antec style full tower case -
the chieftecs look just like them and even COMPUSA sells a tower like
it but obviously I dont know if they all have the same features
inside.

That said - Im thinking of actually buying a case like the one you
mention cause they sell various cheapo versions at Compusa now - like
a barebones black one without the swinging panel like yours for $25
w/o PS. You get a Sparkle PS for $20 300 watts and it a cheap decent
case as long as you dont put a lot of stuff in it. It also feels
better than the case I bought that I disliked. The Antec I bought at
the time which came with a 350 watt antec PS and swinging panel was
tin foil thin. They seem to be making the other types with slightly
thicker steel - its not like the old cases but not ridiculously
fragile as the case I had that dented like crazy if you dropped things
on it. I bought two cases one for a neighbor at the time and one was
dented all up on the top when i opened the box !!! I had to take that
one back and get a new one.

I can't speak for those models but I have an antec SLK3700AMB. It
works well for my new system that I put together. On mine, there is a
120mm fan in the back and an optional one in the front. It should say
on the antec.com website what size the optional fan should be. You
can even order them online.

Yes, I have a 3700. It is a great case although somewhat cavernous.
Actually it would be great for a big fileserver, except you would have
to upsize the power supply. So the 3700's product concept is somewhat
confused.

I'm interested in the SLK1650 because it is a couple inches shorter and
shallower and has the same nice 350W supply. Just not sure about the
effectiveness of the vent in front of the hard drives. I can't tell
enough from the pictures at newegg. I can see that the SLK2650 has good
HD ventilation but only holds two HDs.

Matt,

I don't have that model but I have looked at it a few times. If you go to the
Antec website you can click on the mechanical drawing of the case and it will
give you an idea of the inner frame behind the front bezil.

It's a nice looking case but I don't like that front fan setup. That's why I
didn't buy it. I prefer the front fan to blow directly over the hard drive cage
and it does not appear that would be happening in that case.

Thanks, Ed. I guess I wasn't looking hard enough.

I see the front sheet metal is the same as in the SLK1600. The pdf
shows only a ~40mm vent in front of the hard drive cage.

I believe they can't put a fan in front of or behind the HD cage because
the case is only about 16" deep. The SLK3700 and the Sonata can have
such a fan because they are deeper cases.

Apparently the 1650 is a rework of the 1600 to get Intel certification
for using the case with Prescott or so. The new side vent brings plenty
of air to the CPU, but would seem to take air away from the hard drives.

http://www.newegg.com/app/viewproductdesc.asp?description=11-129-150&DEPA=1

I would think Antec could provide more than a puny 40mm vent for the
hard drive cage. I don't know why they couldn't put a 3"x3.5" vent
there so the hard drives could get some air. Then you could tape over
the 80mm bottom vent, and the rear 120mm would pull plenty of air
through the hard drive cage.

Well, too bad ... disappointing ... I expected better from Antec ...

"40mm" is probably for mounting a speaker, not a fan.

If willing to put tape over bottom fan mount, you might
consider drilling (or cutting) holes in front of the drive
bay, or cut slits so the metal can be folded backwards
(higher structrual integrity than just removing large
rectangular area of metal.

With the 120mm fan in rear and a large opening on front of
the drive bay, there should be sufficient airflow for any
*normal* temp room/environment, also assuming you leave a
space inbetween each HDD, I don't recall how much space
remains if using every mounting slot in that bay.

Here you can see in a photo of the 1600 (similar to 1650) the ~40mm
entity in question :

Thanks. I'm not so enthusiastic about cutting or drilling the darn
thing ...

What tool would you use to cut a rectangular hole?

You can buy a "nibbler" which can start from a small drilled hole and
cut the metal by taking small bites (not bytes) :) from it to cut any
size and shape hole.

Nibbler or sabre saw w/fine-tooth blade... Nibbler being
better for thin cases, sabre saw for thick. I believe those
are 0.8mm(?) so it's borderline which is easier, probably
the nibbler. Sadly due to the case's limited bezel front
intake and the side fan, passive flow will be less than it
could be, partly why i suggested cutting slits and bending,
since it'll allow a larger hole without making front weak.

What about a cut-off wheel on a dremel?

I would probably tape over the side vent fully or partly and the 80mm
front vent fully.

MIght work, i never use a dremel due to how fast the blades
seem to wear out.

That should get the needed flow path, but only you can
measure resulting temp rise... I'm seldom happy with case
front-intake grills in the plastic bezel, that case's front
being typical.

Youll get lots of metal dust , fragments too from cutting and
nibbling.

One thing -- I used the nibbler and it was hell. I used it on the case
which is generally slightly thinner than the frame and my hand fell
like it was going to fall off from cramps after doing it for a while .
Additionally its hard to make clean straight long cuts and in general
it doesnt work well. All I can say is --- anyone who can make clean
cuts with it and use it on anything larger than a quarter of an inch -
WOW. They actually recommend it for cutting a huge window hole on the
side of your case.

I also used it on a thin backplate and the really thin backplate
wouldnt cut , it would bend and curl and jam up the nibble so that I
had clean it out and free it with every try.

One of those hacksaws the kind with the super hard little things glued
on to the blade so that it looks like sand particles are covering the
blade -- those work the best since they cut through almost anything.

Or just drilling a bunch of holes close together for vents would be
the easiest.

If you want to really cut a hole - maybe a nibble used just in the
corners if its a square and a hacksaw might work.

Actually the best thing and Ive seen people modding cases use this but
I didnt think a hole saw would work well with metal but apparently it
does if you get the right kind of blade obviously. Most are made for
wood and wouldnt work well. If you do then its a piece of cake. Watch
out for all those metal fragments which will fly everywhere though.
You wouldnt want a bunch of them shorting your board out.
