post #3121 of 3139
That makes perfect sense. As to the fans directionality, I'm not sure how i should arrange them all now. Taking the 2 sickles out of the equation gives me a very negative pressure setup. i could probably rig it up somehow, but i believe i need to go back to the drawing board with fan arrangement now. The only place for the h100i is where it is. i could reverse the fans, but that screws with the whole directionality again. The 2 corsair fans are 77cfm 4mm h2o each. The sickle exhaust is 79cfm and 2.9mm h2o. The only intake spots i have are the front 200 and the bottom 140. Those are 110cfm and .595mm h20 for the 200, and 70.5cfm and 1.28mm h20 for the cougar. Positive case pressure helps things like my video card fans work more efficiently, so thats what I'd like to achieve. I also am aware that static pressure fans are for rads and heatsinks while airflow is more for cases. If i were to get 2 fans that have a higher total cfm than the 3 exhaust fans, even if the sp is lower, will it still be a positive pressure setup? I would think not since pressure is what we're talking about, i would expect that sp would be priority in this case. if thats true then i need to figure out how to make the h100i fans intake without screwing it all up. Using a fog machine similarly to the video you linked on my case proves you right on the flow sucking butt. front fan blows straight out the side, mostly, and the bottom one is blowing out the side and right back into the sickle on the side. I've been thinking of ditching the hdd cage too. Maybe throwing all 4 drives in the 5.25 bays maybe with a fan blowing across them into the case to open the 200 up completely. Ok, this is my idea: remove the hdd cage and put the drives into the 5.25 bays with the other cougar i have in front of them pulling air in through the mesh bay covers. and replace the side with a solid plexi window with no fan. That will get the cfm in higher than out. My final question in this post is: Will the higher sp in the exhaust fans counteract the higher cfm from the intake to ruin the positive pressure i'm looking to get in my case?

And, I'm talking significantly higher sp, as in 10mm h2o higher exhaust vs 37 cfm higher intake

A 140mm fan fits rather nicely in the 5.25" drive bays if your not using more than one of them currently. That should provide you with your positive pressure your after, essentially the same setup as I have but with higher cfm fans. I have as exhaust two Noctua NF-P12 replacing the stock top 200mm fan and a Gentle Typhoon for my rear 120mm, also worth mentioning is my GPU vents externally which acts as an exhaust, how much CFM it provides, I can't tell you. Intake I have a 120mm fan in the bottom, 140mm fan in my drive bays and the stock CM 200mm fan in front of my drives. This results in a good positive pressure and keeps the dust to a minimum, with the GPU possibly creating a negative case pressure when it ramps of it's fan. I have no hot spots or air dead zones and as a result my mother board rarely exceeds 30 degrees Celsius.

As for your SP question, as far as I know SP is useful when the fan is being used on a radiator or a densely arrayed heatsink, I don't believe it would skew your results because unrestricted the fan can only move so much air.

People in the past have removed the 3.5" drive cage, ascetically the case looks weird without it, how it will effect your air flow is a guess at best, the bulges of the side panels already help catch some of the wasted air from the front 200mm. My guess would be a negligible difference. Adding a fan to the 5.25" bays will provide air directly to your VRM's and your top mount rad very nicely I would think. More so if you get one of those air penetrator fans for the job.

I have seen pics of the sniper w/o the hdd cage and it's a toss up for me as to whether or not i like it. I may or may not remove it eventually. I have done a bit of testing with my rig last several days to see the real world results of having the side panel open or closed. I tried it with the whole side blocked off, the whole side open, and with the 2 sickleflows running. I also added another cougar 140mm like the one in the bottom of my case to the 5.25 bays. It seems from my testing that the cougar in front helps the flow and pressure, like you said, but the side panel being open or closed only gives me 1-2 C difference with my vrm temps... every other temp is pretty much identical in all 3 configurations with the only exception being the vrms get 1-2C hotter without the sickles blowing on them... The temps maxed out at 53C with my 2500k @4.9 ghz and 1.41v. My next test will be swapping the loud corsairs for the sickles on the rad and plexi the side because i'd rather see my pc than have 2C cooler vrms lol. I know the sickles seem to be worse fans, mostly, but the 2 i have seem to be ok and i can handle a 2-3C increase to eliminate the whine of the corsairs at full blast. those things are crazy loud. My tower is 10 feet away from where i'm sitting and i can still hear them over my logitech surround sound! if its more than 2-3C hotter, i'll deal with the corsairs. Hopefully the plexi side will dull them down a little.

there is 1 thing i don't like about this case, the filters. The filtered 5.25 bays are ok and the front 200mm one also. well, the front one is ok only because i removed the metal mesh over the filter to clean it more easily. the bottom and side were a complete waste, though.No way at all to clean the bottom without taking the entire bottom off the tower. The sides just were uncleanable due to the mesh also. My house is excessively dusty and my filters need cleaning every 3-4 days. No way am I disassembling this thing twice a week! I ditched the side 2 sickles and the filter for the time being and also ditched the bottom one, but cleaning that fan is a pain. I need an air compressor and to quit smoking. those two things will probably do wonders for keeping the dust at bay. Especially the smoking... The front filter seems to be a bit useless as well as my front 200 is dustier than the filter. I clean the filter every time i vacuum the living room with the vacuum to keep as much from going in the case as possible and its still filthy and hard to clean without removing it from the case. I have also thrown a pair of led strips in to light things up a bit. If i can still hear the rear sickle with the plexi side when i mount it, I may reconsider replacing the corsairs with sickles. It has been making this incessant whining noise at full tilt and a rattling when i turn it down. I may even try swapping one of the sickles from the door with it as well since it seems to be from a different batch of them. The leds are a bit dimmer and a different shade of blue, but also don't change with the speed of the fan like the 2 on the side panel. It was the first one i bought and it came from a different supplier. Still odd that its noticeably different than the other 2. Aside from any gripes I've made about it, this is still my favorite case I've owned!

I personally removed all the dust filters on my case, I have a wood burning stove in the same room as my PC and for the winter months the soot that would gather on my filters was insane so I removed them from the 5.25" bay covers and cut it off the 200mm fan cover and finally the bottom fan I have is mounted externally in the void created by the bottom bezel thus eliminating the need for the internal filter/fan bracket thing. I do have access to an air compressor and take it to my case every couple months to make up for not having the filters, this has been the better choice for myself.

You should consider getting some Gentle Typhoons, they really have no equal when it comes to sound vs volume. In general you should be avoiding sleeve bearing fans as much as possible and look for fans that feature a dual ball bearing design or even the now more common hydraulic bearing systems.

My cougars are hydro bearings and I have them running full blast all the time. They don't make much noise at all, so I know what you mean. I'll look into those gentle typhoons. I have always been a fan of scythe, anyway. I still have an ultra Kaze 3k around here somewhere from when I was cooling phenom ii's, lol. I love not having to worry about temps like I did back then. Those old AMD's just couldn't take the heat like these Intel I series chips. That Kaze worked wonders for that but it's overkill for my i5

Nice build man, when you have a chance you should fill in the PC specs section of your profile so we know a little more about the hardware. You have some nice accents going with the quick release drives bays and drive caddies. Also gotta love that huge bulge in the back panel, makes stuffing the wires back there that much easier.

Want me to add you to the list on the first page?
