P280 Mod Questions

post #1 of 12
Thread Starter 
So, I just got a P280 and was thinking of some mods I could do to it, both from an airflow perspective and also for visuals. Does anyone know if there is a way to remove just the aluminum panel off of the door? I was thinking of maybe painting that or using some Di-Noc.

My main issue is airflow on the front intake fans though. What I'm wanting to do I can't really describe well in words so I'm going to include some modified pics of the areas I'm talking about. I want to stress these are not my original pictures.

If anyone has the P280 you know that when you place intake fans in the front, there is a lot of obstruction. Here is a pic showing the obstruction I'm talking about.


In this pic you can see those same obstructions with someone's build in it. You can see that they have little ledges that the drive trays slide in to.


Now if I didn't care about using those bays at any point in the future I could just take a dremel and remove those obstructions. Although I only have 3 HDD's, I would prefer to keep those extra bays if needed in the future. What I was thinking was maybe drilling some 1/4" holes in the obstructions allowing air to pass through if the trays weren't installed.

Something sort of like this


Now would I really gain any airflow from doing this? Also do you think it would compromise the structural integrity of the bay mounting system. The front side is metal, the panel inside the case is the same but it is made of plastic. The reason I'm considering doing this is because with my Noctua fans turned up, I'm getting weird pulsating noises coming from I'm guessing air turbulence.

Anyone? I also can't figure out why I can't put a fan in the bottom internal front slot, the one held by those clips. I can put one in the upper slot fine, but any fan I put in that lower one and the fan literally growls. I've tried an Antec Two-Cool, Noctua NF-P12, an Enermax Cluster, a Xigmatek, an Aerocool Shark, and an old Scythe S-Flex and they all growl.

Drilling holes will help but the not as much as you probably want. There will be little increase in airflow because of turbulence created by the rest of the hdd cage.
Don't know if it's possible but
*Can you move your hdd's up into the optical drive bays and remove the hdd cage?..
*Could you cut them out and leaving enough of the track front and back for the hdd mount to fit into? Would be a little fiddly sliding the mounts in but..
*Could you mount another intake in the optical bays?

The front door / venting to front fans limits airflow as well but you could leave door open when you need added airflow (like when gaming)

I really don't want to hack the case up to where I can't have many HDD's if I want to frown.gif . I like your idea about cutting out some of the bracing and leaving enough track in the front and the back, my only worry then would be the structural integrity, as the steel doesn't seem very thick. I can't put another intake in the drive bays as there are 3 of them and I am using 2 of them for a fan controller and a DVD drive. I wish I had the modding ability to mount a 3rd intake on the side panel; even then the way I have my desk, the air there is usually warmer than the front so I'm not sure how much I would gain from that. I'm supposed to be getting two Gentle Typhoon GT-15's today from Amazon that I'm going to try in the front vs the Noctua's. Since they have much better static pressure I'm hoping they can do a better job of getting the air past the door and through the HDD bays.

I still wish I could figure out why any fan I mount in the lower internal fan slot growls. As far as I can tell it has the same amount of blockage as the upper one, and the upper one does fine. The fan slot I'm talking about is #2 in this picture:
.
I currently have my 2 SSD's and one HDD mounted in the bottom 3 bays but I even tried moving them all to the top 3 bays and I still get the growling from any fan in the #2 slot.

I don't think you need to worry about structural integrity.
You could leave the 3rd from top. One that is where bottom screw of top fan mount.
Put your thickest drives in bottom and 3rd from top as these are close edge of fan.

You have 3 side and 2 front intakes, but only top and back exhaust? That's way to many trying to blow air in for area for air to get out. You need same in as out. Total fan cfm rating for all intakes should be a little higher than exhaust. This helps keep dust from being sucked into optical drive, usb sockets, around switches, etc.

I suspect the reason the air on side is warmer than front is because the hot exhaust is circling around under desk and being sucked back in.

I always use fans with a decent pressure rating for case fans. If they can't move air through a cooler properly how can they move air through filters, grills, hdd cages, cables, etc.?

Where did you get 3 side intakes from? This case has a solid side panel, no side intakes. I have 2 front intakes, 2 top exhaust and one rear exhaust. From what I can tell this case was designed with negative pressure in mind. During the summer when I turn my 1850rpm front intakes all the way up I'll probably have equal pressure as I have the top and back fans turned down.

my bad.. miss-read 3 from line above 3rd intake... skipped the line and read 3 intake:o

It's not just the number of fans but the cfm of each fan that determines the case pressure. It's almost no pressure in reality, but enough to keep dust out or suck it in. My case has no exhaust fans. 2x front and 1x bottom TY-140 fans using PWM signal from CPU fan socket on motherboard.. same as cooler fans. Idle 660rpm and max is 950-1050rpm all 6 cores 100% load.

I have that case! The feet are weak and the USB tab on the front panel broke off, so be careful.

I doubt that the fans obstruction make the noise you mention but, did you try swapping the fans? Put the top one down and the down one up. See if they swap noise or if that fixes it. I will try puting my 6000RPM fans in there and see how the turbidity flows.

Yep I've tried swapping the top fan to the bottom as well as trying pretty much every other fan I have down there, they all make a weird noise down there. As for the feet, when I got the case one of them was actually loose and ended up breaking off while I was moving my components in. I contacted Antec and they sent me 4 new case feet even though I only asked for one. I have my PSU mounted with the vent up as I have the case on carpet and the stock feat are only 1/2" tall so the PSU would get no airflow if it was facing down. I've considered getting some aftermarket feet from MNPCTech. They make some cheap $9.99 rubber feet that are 3/4" high and some 1" high ones that are made of aluminum but they cost a ton ($39.99). I've always had good experiences with Antec in the past. On my old Antec 902 the plexi on the window was cracked around the mounting holes and they sent me a whole new side panel. I have very few complaints about this case. They definitely could have made the top out of thicker steel because the way it is now, if you put powerful fans up there the whole top of the case resonates. They also should have put options for 140mm or 120mm fans for the top. Heck I would actually have preferred just one 140mm hole vs two 120mm ones. Only other complaint is the paint seems to chip pretty easily, already chipped a little paint around the screw holes on the top fans since I've had to screw and unscrew them so many times; a flat black touchup pen made that not near as noticeable though; if I had some semi-gloss touchup paint it would probably blend even better.

Oh ya. I noticed some chips too. Good tip.

Try getting some dampening on the fans. Silicon pad or non stick. Even some O rings from your keyboard mods if you have leftovers. Dental bands. Just put some rubber between the fan and the case. I have the top 3 at low so I never notice any hum there. But do you really need 2 fans there? The stock one does me fine. But I have the PSU on bottom vent out, so that helps.

As for case feet. Go to the hardware store. Look at door handles/pulls for chests, shelves and such. There are some nice ones that fit right on. Cheep and good looking. Make sure the bolt is not too long though.
