If you have the top radiator blowing air into the case, you will need to likely set both the front and rear case fans to exhaust as you will have two rads blowing in. Positive pressure is a good thing, but too much is not. However, if you have the rad exhausting air, you can set the rear fan to intake and feed fresh air across the MB heatsink as well as providing fresh air to the top radiator. I am going to be trying with the rear as intake and as exhaust and seeing where the temps are affected. I have 4 case fans (1 rear, 1 interior, 2 front) that are all 140mm, 4 120x25mm 107cfm rad fans in the bottom blowing in/up, and 6x 140mm 103cfm top radiator fans that will blow upward (exhaust). I would think that a rear exhaust fan would not be of any use as the 2x more powerful top fans should get any air first, so I am wanting to see if feeding in cool air from both sides keeps temps better and helps reduce the air temp increase from the bottom rad.

To Electrocutor:
Ok, even though they won't seal it I will still get them. Will I have to buy longer screws to fit them in? Are the cougars good case fans not just for radiators, but as exhausts or intakes just for the case?

To nleksan:
Is it ok to use a combination of fans on the same radiator, for example 3 cougars intake on the radiator and then on the inside I have a different fan pulling for push pull?

I think that I will get an EX 420 if I can find out how to mount it otherwise an EX 360 (The Top), an EX 280 (The Bottom) and possibly an EX 140 (The Top Of The Back Panel push pull with cougars).
post #53 of 115
It is generally best to use the same fans, as speed variations can supposedly cause issues. I can't speak to the subject any further than that, but hopefully someone else can chime in.
However, if you have the rad as an intake, all fans will be blowing downward, so I would think that having Cougar fans on both sides will be fine. You don't blow air into the rad from both sides, so if you are certain that you want it as an intake, go ahead and get the Cougars.

The way to fit the EX420 is to align the front most fan holes and then simply measure back as to where you need to drill the new ones. The radiator will then fit just fine.

For the bottom rad, I highly recommend sticking with a 240 as the modifications required to fit a 280 rad are much more involved than fitting the EX420 up top. You will have to cut away pieces of the front fan intake mount, which also means no lower front fan.
The ideal way to go, IMHO, is with a super nice full-size 240 such as the Alphacool NEXXOS UT60 240, which will fit in push pull even with its 60mm height, allowing you to keep the upper drive cage as well as the front intake fan.

Fitting a single 140 rad is not quite so easy, as it will block the top rads fittings either partially or completely. I suppose you could mount it to the interior fan swivel mount, but that is not something I have seen much of so I don't want to mislead you thinking that it will work if it won't.

To nleksan:
Ok a 240 radiator, would you think ap 15s would do well there? If cougars are good as normal case fans I will get them for that job. Would I be able to fit a 120mm radiator there then?
post #55 of 115
AP15s would work, and are geared towards providing good performance at a low noise level. There are certainly much better performers, but they will be louder. I usually recommend getting a fan controller and faster fans (i.e. Gentle Typhoon 2000rpm+, Delta, Panaflo, Sanyo Denkei, Akasa, etc). That allows you to have quiet when needed but doesn't limit the performance of the system by the fan speeds.

I do think that the AP15s get praised a bit much, as they are good fans but there are certainly better performance fans as well as much quieter, the GTs just do the best at compromising between the two in many people's opinions. I personally went with Koolance 120x25mm 2800rpm Fans push pull on the UT60 240 as the radiator scales so well with fan speed, I'd much rather have the ability to take advantage of that than not. Plus, $7 for fans with 5.4mmHg pressure? Yes please! They also make the same fan except that it's 38mm thick, and they also make a slightly slower model of the 2800rpm version that is otherwise identical. Plus the ball bearings means that you can mount them however you want without worrying.

A slim 120 rad would possibly work, but I don't know that the cost would be worth the likely negligible benefit... You would maybe drop water temps a degree or so, but the case airflow would be significantly reduced resulting in higher temps for anything not water cooled. And honestly, with an EX420 and UT60 240 cooling a CPU + 1 GPU, you are going to get phenomenal temps anyway... I would guess around a DeltaT of 5C give or take. The two rads are more or less equivalent to one 360 rad per component, which means that each 120mm's worth of rad space is only dissipating around 50W at full load on stock speeds, while the recommended amount is 1x 120 per 100-150W of heat. This means you will have a ton of headroom for overclocking with no real worries regarding temps.

They're good case fans too unless you're looking for the ability to chuck air like a monster (NZXT Enthusiast/High RPM Silverstone): If you're looking for quiet, you can't beat the Cougars.


For 120mm: if you're not using a fan controller: AP-15; If you are, you may consider the AP-29 instead (the AP-30 and 31 are much too fast to be quiet, but at it's lowest, the AP-29 can be pretty quiet, though not as well as the AP-15; but the AP-29 can also be ramped up). I _would_ recommend the Corsair SP120 as this speed variance is at the sweet spot, but if you're talking about the bottom rad pulling air upward, it suffers from the same upward direction airflow bearing issue as the Cougar as well as the same non-square frame issue (if it matters). I'll note that the upward airflow issue with the SP120 is not as much of an issue as with the Cougar, but is still audible if you're listening for it. It doesn't give you the 'that can't be good' feeling though.

Ok I did not think that I would need the extra radiator, it was only if I wanted it after I had made the computer. As I have found only a limited range of fans here in Australia for 2kish+ rpm fans I only found the cm sickleflow 2k rpm but I heard that CoolerMaster lies about dBA. The Koolance 4k rpm it is the only koolance fan I could find, I will not get it though. Silverstone 120mm Air Penetrator Fan AP121 they look ugly but I do not know how good they are. Scythe 120mm SlipStream 1900rpm Fan I think they are good as far as I am aware. Scythe 120mm Gentle Typhoon 1850RPM Fan which are the ap-15s. CoolerMaster 120mm Excalibur again about the dBA lies. CoolerMaster 120mm Turbine Master 1800rpm, again CM and very circular. Cougar CF-V12HB which I assume has the same bearing problem as the 140mm. Then the corsair fans, and noctua but the noctua's distinctive colours are painful to look at. I can also get from some other companies, but I don't know their quality like. Swiftech, xigmatech, thermalright, Nexus, GELID, Enermax, Antec, Arctic Cooling, and Bitfenix fans. That is from most of the websites on static ice.

But I can use www.thekoolroom.com to find other products, but I have to pay more because they are a small niche supplier. Which allows me to get Yate Loons, Akasa, ALPENFOHN, Reeven, Phobya, BeQuiet, Aerocool, coolink and many others, too lazy to say all.

Still can not get those Koolance 2800rpm fans but I can get the 2600rpm ones ($15)

That is great news about lots of overclocking headroom smile.gif I will try to get some healthy overclocks that I can game at, but benchmarking may also take place at LAN events or just because I want to smile.gif.

To Electrocutor:
I think I will get some of the cougars but only as case fans, so I do not have any hassle with my radiators. If I were to get the ap29s ($29) it would be from the niche seller that I just mentioned earlier, as they are the only people I know that stock them. I am interested in the Alpenfohn fans but I don't know what the sleeve bearing is.
post #58 of 115
The 2600rpm Koolance fans are the same design with just a slightly slower speed, as far as I can tell. They are fantastic fans for 120 rads (120/240/360/480). If BeQuiet is the same company as Bgears, and I think I have heard that they are, then the Blasters 140mm are perfect for the EX420. Bitfenix Spectre Pro are also nice fans, and if you get the Bitfenix Hydra Pro 30W per channel 5ch fan controller, you can control the fan LEDs on the Spectre Pros.

Akasa Apache and Viper 140mm fans are very good rad fans, and the Apache is slightly weaker but isn't ugly yellow. It still has right about 3mmHg which is very good, and I strongly considered them myself.
The Swiftech Helix fans are essentially a cheaper Gentle Typhoon AP15 in terms of noise and performance, with slightly better airflow but also slightly more noise.

The EX420 requires 140mm fans, so the options are much less than with 120mm fans, but that doesn't mean that there aren't good options. Here is a list of what I would consider to be very good 140mm rad fans:
- Bgears Blasters 140mm 1800rpm
- Bitfenix Spectre Pro (PWM model if available)
- Akasa Apache
- Akasa Viper
- Rosewill Hyperborea
- NZXT FX140LB
- Prolimatech Vortex (the aluminum ones)
- Yate Loon DH14SM (140mm medium speed)
- Gelid Wing High Speed 140mm

All of those should be good for your EX420, and I don't believe any of them have issues blowing upward which is a good thing. I prefer having the top radiator blowing air as exhaust, but either way works (so long as you have all fans on the radiator blowing in the same direction).
If possible, I would suggest going push-pull, especially if you will be using a single rad initially, as it can add 10-20% performance as well as provide equal performance to a single side setup but at lower speeds. Especially since the radiator uses 140mm fans, which don't yet have as much static pressure as some 120 fans, the use of push pull can make up for this difference. It also helps to reduce the "dead spot" in the center of the fan where the hub sits. One of the great things about 140mm rads is the significant increase in surface area, so increasing the effective surface area even further is a very good idea IMHO.

Since you should have plenty of room, you could consider using Phobya 140mm "shroud/decouplers", the rubber ones that are only 7mm thick. They help by sealing the fan-rad connection, reduce any vibration noise, and the 7mm gives a shroud effect in which the air is able to hit the rad much more evenly than when the fans are mounted directly to the rad. You would only need to put them on the push fans (the inner fans, not the ones in the "stealth fan bay" up top under the vents). They are inexpensive at $4 a piece or so, and while they may or may not have a significant performance impact, they will definitely work as sound suppression/decouplers. Also they will ensure that there is no air escaping from between the fan and radiator, which means that you will get as much of the fans static pressure as possible.

To nleksan:
I looked at both akasas the viper and apache are both fluid dynamic bearings same with both BeQuiet fans. Why are pwm models better I know it is the 4 pin plug but how is it better. I can get the Yate Loon medium speed ones for $8! (62 cfm on the yate loon medium speed it doesnt sound like a lot) Or the phobya g silent 1400rpm, noiseblocker pk 3 1700rpm fans, or ALPENFOHN 140mm.

For the 120mm I can have ap15s, ap29s, phobya g silent 1600 or 2000 rpm, yate loon 1350 or 2200 rpm, the swiftech helix. It seems like the Koolance 2600rpm, the yate loon or the ap29s are the way to go, what is the Koolance's sound like just on average settings for daily use?

The Alpenfohn fans look great and would be nice and quiet but I wouldn't be able to crank them up if needed, other than that they sound like they would be great (what a pun). If I had no intention to overclock I would get them, they even have a three warranty on them.

The yate loon D12SH are really powerful if I want to crank them up, I can just keep them on low most of the time.

Edit: I just found cougar fans without the liquid bearing it is a hyper spin bearing does anyone know what that bearing is and if it means I could use them for my radiators?

I guess the absolute most important thing is to decide which rad you want, as a 420 requires 140mm fans (120 will not work) while a 360 requires 120mm fans (140 will not work).
Yate Loon DH14SM are actually quite decent fans, and while they use a sleeve bearing, they are so cheap that it really is no big deal to replace them now and then, but if you are able to keep them well lubricated (synthetic motor oil, specifically Royal Purple or Redline 0W40 is what works best for me with sleeve bearings), as well as maintain them religiously in terms of removing dust, they can last many many years.

If you decide on a 420 rad, the Akasa or Yate Loon are your best bang for your buck.
If you choose a 360, the Swiftech Helix will provide best performance per dollar while being not too loud, but the Koolance 2600rpm (I just looked at mine, and they are indeed 2600rpm, apparently Performance PCs has them listed wrong) will be the absolute best performance possible out of anything you have available, bar none, but I highly recommend a fan controller (Bitfenix Hydra Pro). Actually, regardless of what you decide, still get a fan controller.

I don't know if the other Cougar fans are susceptible to the same issues, but I would bet on it. It seems like they are essentially the same bearing design at the basic level. Also, I have never heard of issues with Akasa fans, so it's possible that they use a more resilient type of Hydrodynamic Bearing?
