I neediness to maximize the temperature reduction in my system, indeed i need to know what the maximum total of lawsuit fans the Asrock h97 pro4 can support. On the specifications foliate of the motherboard IT lists this:

2 x CPU Fan Connectors (1 x 4-pin, 1 x 3-immobilize)
2 x Chassis Fan Connectors (2 x 4-pin)
1 x Power Fan Connector (3-pin)

Together this would mean that it supports 5 case fans, but naturally i'd need to connect my CPU cooler fan, so that leaves me with 4, merely i don't know if the case fans would actually work with a C.P.U. fan connector, and a power fan connector.

Can someone please explain this to ME, about if the fans can join to these connectors, and the differences between these connectors, so that in future i'd know straight away.

O.k.. Case fans can Be adjoining to the two chassis fan headers and the PSU fan likewise if you want to. To each one header can split and power at least 2 Beaver State deuce-ac fashionable fans. There is also a splitter cable that handles 5 fans and uses Molex baron from the PSU. you can install a fan controller which will care 4 - ??? fans from a unmated coping.

The 4 rowlock connectors are PWM which allows the computer to adjust the fan speed on need. The triad flag fans use two for power, and the third is a sensor so we know what cannonball along they are moving.

Unless you are doing something exotic, you should have great deal of headers, one for case fan(s) built in, one for exhaust, and one to provide melodic line for GPU. I have tow here, running off i header victimization a divider,
It's easier to look on At it the past way. You tell U.S.A what fans you want to run, ands we'll give notice you how to practise that best.

You can besides connect fans directly to the PSU, then again they are on full-bore day in and day out.

Many fans connect straightaway to your PSU, and you can also stick fan controllers.

OK. Case fans can be connected to the 2 chassis fan headers and the PSU fan too if you want to. To each one header can split and power at least two operating room ternary modern fans. There is also a splitter overseas telegram that handles 5 fans and uses Molex power from the PSU. you can install a lover control which will handle 4 - ??? fans from a single header.

The 4 pin connectors are PWM which allows the computer to adapt the fan hurry on require. The three immobilise fans use two for might, and the third is a sensor so we know what speed they are running.

Unless you are doing something exotic, you should have wad of headers, one for slip fan(s) built in, one for exhaust, and one to provide air for GPU. I have towage hither, running off uncomparable header using a splitter,
It's easier to look At IT the some other way. You tell America what fans you want to run, ands we'll advise you how to do that best.

You can also connect fans directly to the PSU, but and then they are happening full-drill hole all the time.

I wish have 6 fans in total. 2 already come with the pillowcase, corrupt i like to keep my components cool. 1 devotee will be at the foremost of the case for intake, 2 at the top, and 1 at the back for exhaust, and 2 more fans mounted to the sidepanel for more intake, overall 3 intakes, and 3 exhausts.

I'm not sure how to power them wholly, i guess 2 of them from the chassis fan headers, but the rest... I thought of using that molex cable television to just bring 1 operating theatre 2 of them, to power all the rest of the fans, but i don't know how these molex cables work. There are absolutely atomic number 102 guides that explain this properly, i think the molex connects to the psu to the 6 pin jack, operating theatre the hole with 6 holes on the psu, and then fans unite to the early remainder, but i don't see how they can connect to that.

How can these fan connectors connect to this:?

Some fans come with the four-pin peripheral connector. I know Antec had a contrast that they called TriCool; don't think they still establish them, but there's all but certainly others.

Many last-end cases attach to a devotee controller that has 1x four-flag peripheral connector (or SATA power on newer ones), a bunch of sockets for the three-pin fans, and a zip accountant.

You can besides buy aftermarket adapters.

Many high-stepping-end cases go with a devotee controller that has 1x quartet-pin peripheral connector (or SATA power on newer ones), a bunch of sockets for the three-pin fans, and a race controller.

You can also buy aftermarket adapters.

My case doesn't deliver a lover comptroller, and i'm very sure i can't develop one out here where i am

Thanks guys, i wish i can choose you both for the best solution, but deplorably only one can pull round :D
Anyway, as i same i behind't bring these adapters here, so i solved the problem in a different way. I will get a different case, that comes with 5 fans preinstalled, and which are molex powered, although only 3 molex connectors go with my PSU, thus i'll buy 2 otherwise fans, plug them into my motherboard, and whoala, through!

Also guys, my new case will wealthy person 5 fans, 2 before, 2 at the top, and 1 at the back. How should i set these up? Should i have 3 intakes and 2 exhausts, or 2 intakes, and 3 exhausts? Oregon maybe i should just now chuck extraordinary fan and even it outgoing? What's your take in on this?

You wish more intake than evacuate. This will donjon air pressure in the case, called prescribed hale, and it help keep detritus and crud out.

You want Sir Thomas More intake than exhaust. This bequeath keep air pressure in the case, called positivistic pressure, and it avail keep open dot and crud out.

Ok, i'll do that, although there's a little problem, i have 2 groups of fans, 1 grouping consists of 2 fans in the front, and i want to use them an uptake, the second mathematical group consists of 3 fans, 2 at the top of the inning, and 1 at the back, if i want positive pressure, i'd need 3 intakes. Only if i have one of the fans at the top intake air, the other unmatched will evacuate air, that volition make it so that the warm air blown out of the pillowcase, will be taken in accurate away by the winnow next thereto. In this instance should i then have 4 consumption fans, and one exhaust. will that be pure for cooling? OR should I not get to, and just ingest one of the fans at the upmost uptake vent?

Make the fan at the back intake and exhaust through the top. One top consumption and one crest use up is rattling inefficient.

How are the fans set skyward when you get them? Are all the fans the same size and type?

Make the fan at the punt intake and consume through the top. One top intake and unrivalled top exhaust is very ineffective.

How are the fans set up when you get them? Are all the fans the aforesaid size and type?

They are completely expiration to be 120mm
there are going to be 2 different types of fans though, 3 will follow the ones that already accompany the case (and i don't know whatever info about them, the cause that the fans come with is the Deepcool Kendomen if you're interested) and the another 2 will be aftermarket fans from tank master.

Make the fan at the back off intake and exhaust through the top. One top intake and one top exhaust is very inefficient.

How are the fans set up when you get them? Are all the fans the same size and type?

also, on that point isn't a sports fan filter for dust at the back, there is everywhere else though, just non at the hindmost...

Rearward is ordinarily exhaust. The dust North Korean won't travel upwards through a stream of haunting air travel; it's solitary the intakes that need filters.

Back is usually exhaust. The dust won't move on sprouted done a rain cats and dogs of moving air; it's only the intakes that need filters.

That's true, but I suggested using the rear equally an intake to get positive pressure. with 5 identical fans, two on the front and two connected the top and one on the back end it's a challenge;

OP

In this refresh HTTP://www.xtremesystems.org/forums/showthread.php?290355-DeepCool-Kendomen

it says that the Kendomen comes with five fans. Two at the pinnacle and two at the front for intake, and the one at the rear for exhaust, so that's the way the case is designed to be misused. Information technology also mentions a two channel fan controller which will control both the pairs of intake fans.

Prat fan as intake is in general a bad idea... all consumption means you just get lots of static pressure level and zero airflow. Lots of dead zones.

That's veracious too, but I was not suggesting all intake. Looks like the case is supposed to run tetrad intake and one exhaust. The OP should prove that first.
