I am wanting to get a EX 280 for upfront and cut out metal obstructing airflow at inside front front ( the strips for fan and rad mount down the inside that pass right over the best part of the fan blades ), just cutting a disk out each side to follow contour of the fan casing ,each side.

I like the idea of utilizing the 140mm front opening fully, and I will be exhausting out the front, and on the subject of fans, I was originally going to go with SP120's through out case, but now I'm going for the Aerocool DS 140mm ( I have compared them to SP120 in basic tests with restriction and no restriction and they feel a lot better on both tests , just by feel of cool wind on face very unsophisticated but effective lol )

So I have read lots of forums and opinions, about what rad better,what fan better this config that, and the feeling I get is that it is splitting hairs and as long as you getting good static pressure and air flow and enough rad surface area then it will be fine.

So do you like the Idea of 140mm on a 280 rad up front maybe even push pull unobstructed ,exhaust , filter removed, and metal removed to increase flow, I like this idea and think the DS fan great personally, though some on Daves fan debate forum disagree prfering Delta Noctuas of Jetflow ,I like the aesthetics of the DS 140 and the Akasa Viper 140, but i do have concerns about the Vipers PWM tick ?

wasnt quite sure what you wanted my opinion on but from reading above Ill give you my opinion on everything you said! I wouldnt cut the metal inside the front to allow more airflow personally I feel the airflow is good in this case! I know it looks like it needs help but Its pretty good overall in the front, best thing to do to increase airflow (if you need it) just remove the front panel cover on the front part of the fans!

I also wouldnt make the front a exhaust! I would keep the front and bottom as intake and top / rear exhaust! reason is just common knowledge "hot air rises" and its easier to pull it out of the case from the rear and top rather than trying to shoot it down to exhaust out the front and bottom! Also if you keep the front and bottom as intake and top and rear as exhaust you keep positive pressure within the case resulting is less dust build up! As far as fans to use, that just a personal preference! I like corsair for the color options and for me they do a great job! As far as push/pull configuration on rads. If you have a rad that is 60/80mm thick I would use push/pull on it as for its a big rad and it would help out to have air hitting both sides to allow it to cool than one fan pushing or pulling trying to get air through the big rad! now if the rad are 25/30/35mm thick push or pull is the way to go doesnt make much of a difference really. my 360 rad on top is in push while my front 80mm rad is push/pull and my bottom 240 rad is in pull mode. but it doesnt really matter or makes little to slight difference in the way you put fans to your rads! Just 60/80mm thick rads I feel is best to have push/pull on them since its more restrictive and bigger surface area!

Thanks for feedback on all points,just good discussion all round for this thread ,and any water cooling subject, sorry was not clearer in question but I guess was more specifically about 280 rad verses 240 and 140 vs 120 fan choice

I have a different view of which I'm pretty sure about ,and will stick with my plan of Intake and exhaust, I don't like the idea of blowing hot rad air into case (iv read all debates pros cons ) I far prefer to bring fresh cool air in and blow hot air out, if you bring cool air into case,you always have cool air for rad, and as far as hot air rising ,it has Zero time to rise IMHO as it is under constant flow and turbulence not rising at all just full fast flow from bottom to top and bottom to front ,also I will have rear as intake too, so 3 unrestricted 140mm intake fans suppling 5 restricted exhaust fans at least 3 of which will be SP 120, so I think with My FC5 V3 fan controller and the restriction balance with rads vs no rad fans and 140 vs restricted 120 ,that I will be able to dial in as much positive pressure as i like, by balancing the RPM's.

I'm very reluctant to blow rad air in so, I will have to make 5 exhaust vs 3 intake work !, if result not good ill change it.

And I am strongly considering the front panel mod, in fact I will but not until I have got another spare panel to work on, I'm doing a lot of mods cutting a lot of metal out, and it is fine to, Iv assessed it and talked to JR23 , im doing a full Acrylic mobo tray mod, and cutting out 5.25" bays and putting new mounts for FC5 V3 and NZXT RGB, as I will also mod the front 5.25" bay panels and re mount my 5.25" forward flush with front of case instead of recessed, I will be starting a build log very soon probably in just 2 days time. thumb.gif

Food for thought, for anyone, I personally don't think it is a big mission to cut out the metal in way of fans,I understand it is initially a little weakening , but very easily strengthened again by simply mounting the fans and rad,as that will make it fully rigid again, and not really that weakening anyway, as that area gets most of it strength from the upturn on the side of the mount area , but I would probably still mount a new bracket on the Rad mount portion.

I know you are most probably fully right in your comment nkd90 that the fan gets plenty of flow, for me it's just as much about the build and the mods that interest me most ,more than using the PC at the moe lol, I just think that ultimately it can only improve the flow and will be a joy to do. ( not seen this done before ) Warning: Spoiler! (Click to show)

This looks like a lot of steel in the way of those blades:D

IMO there isnt a difference between 240 rads and 280 rads as for this! 240 rads are quite compared to 120 rads as for 140 fans rpms are lower. But the other difference in rads is this:

1) low FPI rads can use lower rpm fans to essentially cool just as well as high FPI rads with high rpm fans, I have never owned any low FPI fans but just from reviews on others it supposively great for people who like absolutely silent rigs.

2) others will argue (myself included) the higher FPI on a rad the better cooling results you will have as for it has more surface area but you will need a higher rpm fan to accomadate air flow through the more restrictive FPI rads.

I have 10 fans hooked up to my 6 channel fan controller (through 3 split fan connectors) and I can control how quite and loud they are much like you will be able to with your fan controller! But even with all 10 fans cranked high I dont feel like they are really that loud! but "loudness" is a personal preference and differs person to person! I always say get higher rpm fans with a fan controller because if you need them you have them and if you dont need them you can turn down the rpm to desirable level!

I haven't purchased a lot of fans that are known to be the best for rads. I have only bought corsair sp's as for the color scheme matches my case and loop I have going! But they work fine for me! I am lead to believe noctua SP are better but I just dont like the looks of them they dont have any eye candy in my opinion lol

Now you mentioned you didnt want to blow hot air inside your case and I understand that. Just wanted to through my system at ya to get an idea that it really doesn't

room temp 74 degrees

intel 4930k , two gtx 660 ti (have 2 gtx 970 just waiting on waterblock) and three rads inside my case stay at 78 degress Fahrenheit and components mainly run at 34- 36ish then depending on what stress test they might climb to 40 degrees while inside of the case stays pretty constant at whatever it was before I turned on PC here lately its been 78 degrees.

also here is a link to buy a custom front panel to allow additional airflow you can buy or DYI lol

link: http://mnpctech.com/mnpctech-clear-case-pc-panels/corsair-750d-front-plate/

I have also seen people cut a big rectangle out of the panel leaving about a inch around the entire panel and glueing or 3m tape modders mesh to have additional airflow!

Ha yeah ,you pretty much come to same conclusion as me, all the threads I'v read say there is not much difference in temps no matter what you do with air, just that you have enough flow and enough rad surface,in a general and "basically summed up".
And yip ,quiet vs a bit of noise, I want quiet but dont care about noise if im on the end of a machine gun or got a V12 screaming it's head off lol.

Yeah rectangle cut out was mod i was talking about ,probably not necessary if filter taken out, ( in my case )
Thanks for link and feedback
And my final fan choice is now as much to do with aesthetics now as the Akasa 140 viper or Aerocool DS 140 or SP120 all good enough for me, and there are some better performers but they are butt ugly or plain jane:D

yes very ugly or plain jane indeed! And yes it all about the same result in the end. Water cooling is mainly about personal preference in the end. What are you wanting to achieve with looks, build, and coolness of components, and budget! But If I had only two rads in this case I would probably go with 360 rad on top and a 280 in the front as for that 280 has more surface area than a 240 which would keep things cooler even though it may not be by much! But since I have three rads I had to go with two 240s as for having a 280 and a 240 dont fit in this case or atleast not for me since I have a 1200w psu. But I dont think you can have both I think it comes very close to fitting but not close enough!

I did a write up on the front panel mod awhile back. Here's the link in case you did not see it.

My RX360 + Photon 170 kit came in today smile.gif so dang happy. The RX is so dang big. Also ordered an RX240. But the photon 170 pump combo is a pure beauty! I can't install today because I'm too busy with homework, and tomorrow I have school and work till midnight. Can't wait till Thursday though!!! smile.gif
