Help with my cooling project

I am building a W/C system in a new case, see this thread and this thread. I am now re-thinking about the airflow etc. I may consider the traditional plan of mounting the radiator in the lower front and hog out the case to acomodate it. I have concerns about the front panel and really don't want to mess up my new $150.00 (not incl PSU) case. There is the front of the case itself which is no problem but there is also a front panel with aluminum under Lexan (1/4" from the front of the case itself) with holes in it (I would plan on making enough new holes in the same pattern to accomodate the area of the radiator. The front panel is only 1/4" from the actual front of the case and will not allow enough air through the bottom as the sides are flush with the front panel. Will the added holes be enough??? I also plan on keeping the 80mm fan above the place I am considering placing the radiator (measured and it will fit!) for some fresh air into the case and using the existing (1) 120mm and (2) 80mm fans for exhaust.

pic 1 shows the actual case front and where I will cut for the rad.

pic 2 (left) shows the front panel and about where I will extend the holes.

pic 3 (right) shows the clearance between the front of the case and the front panel.

    you could always have a seperate box for it outside hte case and just have some longer hoses IF you have a good pump


    Saves you from tearing up your nice case!

    Wow, mtgoat... I can't be of much help since I have zero wc experience, but good luck to ya! However, my common sense tells me even an expanded series of those holes might not let enough airflow through to properly cool a radiator...

    My recommendation is to get a bigger case. I wouldn't feel right modding a $150 case to that extent.

    As far as front panel goes, 1/4" isn't going to cut it. I have an intake like that on my IBM PC300GL (3/4"), and it's barely sufficient for a single 80mm fan's throughput. Adding holes will help but I've got another machine whose front panel is pinhole-riddled and it gets poor airflow that way (air is a fluid, it sticks to surfaces). You're going to need slots (1/4-3/8 x 1" in a pattern) or large holes (1/2" dia) to get decent airflow. If you go for the holes, use a drill press if possible so it doesn't look like the mad hand job it is. A router with a home-made jig and clamp might work for slots.

    BTW, if you're mounting the radiator there, where's the PC speaker going to go?

    I just don't understand why you have to go modding the case? couldn't you just set the rad right there inside the hd cage and move the hd's up into the 5.25 area? wouldn't the rad/fan get enough through the existing fans?
    What am I missing here?

    That's exactly what I'm afraid of. And I don't really want to go any farther with modding the face than that. I may just end up going back to my original plan of putting the radiator in the rear 120mm hole and open the bottom front fan to a 120 and add some holes to the faceplate.

    I really don't have the space for a separate box but it has crossed my mind!

    Those are 80mm fan holes there right now and the fin area of my radiator is 5 1/2" by 5 1/2" by 2" thick. I also have a shroud to put a 120mm fan on it. I have decided to eliminate 2 HD's and mount 2 in the floppy bay and one in the bottom 5.25 slot to eliminate the cage completely if I need to to mount the radiator in the front.

    Here is the radiator I will be using.

    Larry, looking at your plans there, a couple of thoughts crossed my mind. If you mount the radiator low like that and have the fan draw cool outside air through it into the radiator, you will be blowing hot air inside your case. That is the position I mounted my radiator in my SX1240 Antec but I mounted it so that the air exhausted instead of being blown into the case. Then, I ran into terrible airflow obstruction with the faceplate of the case, so I had to cut a hole straight through the faceplate(used a 4 inch pvc coupling to route the exhaust past the faceplate. You wouldn't want to do that with that nice case you have. I would say that your best bet would be to somehow fit the radiator/fan/shroud to the back 120mm exhaust hole for the best way to keep that case looking neat and clean.

    I see the Dimensions(with tanks) are 5.5"W x 6.38"H X 2"Thick dimension ...what are the dimesnions of the one you will be sending back?

    I assume the rad will fit between the sides in behind the front bezel? If I understood correctly you are planning to, perhaps, drill a bunch more holes through the lexan and aluminum bezel to allow for airflow to and through the rad.

    I think I noticed that there is a bottom intake under the bezel area. Why not make a cowling out of sheet metal for the rad. The cowling would go sides and top of the rad so air would come up through the front bezel intake and be directed into the rad. No warm case air would be sucked into the rad from inside the case.

    It's that or tuck it up over the PSU...if room.

    It's a bigger project and involves a bit more cutting to the face plate but....I went to Home Depot and spent 1.74 on a cheap aluminum cold air vent, then cut out a piece, cut the appropriate hole, then used silver automotive door trim around the cut. Gets great airflow.

    As to bringing in warm air, the air that has passed thru the rad is only very moderately increased in temp and is still valuable as cooling air to the box, imho.

    I appreciate all the replies and good ideas. I guess i now need to digest all this and formulate my plan of attack.

    Bigger case??? This case is 20"(H) x 8.6"(W) x 19.0"(D) (bigger than the 1030 series Antec cases). As for modding a $150.00 case, that is part of my dilema. I would find a spot for the speaker.

    I take it it isn't as bad as I thought to use the air from inside the case to cool. Especially if I manage to keep a good airflow moving through the case so it never gets much if any warmer than the ambient room temp. What you suggested for radiator location was my original plan and after getting my case stripped down further I realized I could mount the rad in the front but was uncertain about restriction.

    csimon
    The one I already sent back is 6"W x 7"H X 2"Thick. It is
    this radiator.

    You are correct in that the radiator will fit between the sides of the case, I was planning on drilling holes and there is an intake under the bezel area. The gap between the bezel and case is only 1/4" and I was considering making more holes to match the ones already there but now having second thoughts and not sure it would be adequite enough. As to the area above the PSU, there is no where enough room for my radiator and it is higher than I want to put it as I am trying to keep my loop within 1 foot high (not counting the resivoir.

    keto
    I would consider what you outlined if not for the Lexan on the face. I do like your idea if my case was just aluminum on the front. Couldn't I potentially keep things cooler by using the case air to cool, especially with the 2 80mm fans above the PSU?

    Well, you could get a fan filter, cut out the hole area, mount fan filter, and duct rear of rad to hole in bottom of case. Then raise case 3-4" from floor on a 2x2 frame. I would, if you do this, stick a fan in bottom of duct lowing down. Suction plus front fan, suction horizontal and down blowing, front vertical and inward blowing. Essentially a push-pull fanning with a ducted bend. I have this not-so-little visegrip, it is a metal bending jaw vise grip used by HVAC techs.... Nice for bending aluminum 10-18 guage sheet metal. Liquid solder seals ducts ok....

    That would eliminate hot air in case problem.

    ADDED: One more Idea-- take some sticky back black closed cell foam and stick on outside of duct, then if you put a side window in you end up with the duct hidden, or paint the duct dull black on outside.
