All about Closed-loop Liquid Coolers

its doesnt matter MUCH weiher the hose is up or down, thats why a pump is there. you want better cooling efficiency, get your rad fans to such cooler air

this has always been a dilemma for me, if I suck cool air from the outside, im puting hot air inside my case, which heats up my mobo... Now, I just try to keep my case as cool as possible, and have the rads as exhaust..

nahh.i just changed my VC from zotac closed shroud vc to MSI dual-fan open shroud vc...
because i thought open-typ is the better one...
and I myself found out that the closed-typ vc itself is hottier when I touched it while running.

Closed Type VC is better if you have a closed case, like the ones Im using, the Silverstone SG09 and SG05.. but for any other cases, that are a lot bigger, open shrouds are better, I just cant imagine putting an open shroud 7870 on the SG05, CPU temps would suffer!.

Bro this is what my fren in tpc said:
-If you want a cooler CPU make your radiator fan intake.
-If you want a cooler casing make your radiator fan exhaust.
i think he's right.

^ korek... since cooler air is sucked-in if the rad fans are set-up as an intake... and if the rad fans are set-up as an exhaust, hot air from inside of the chassis would be sucked-out and used to cool down the rads.

for an exhaust system, it would be better to use high RPM fans (2K+ rpm) and set it up in a "push-pull" configuration so as to compensate on the temp of the sucked air... saba lang ni gamay gyud sya... but it will depend on the rad fans used hinoon...

pahabol... mas abog ang sulod sa rig if the rad fans are installed as an intake... kun butangan ug air filter, efficiency in cooling down the coolant inside the rad would suffer... even wla'y air filter, need ug maintenance gyud sya... limpyohan permi para dili mag pundok ang abog sa rad... if daghan abog ang rad, efficiency in cooling down the coolant inside the rad would also suffer...

the same lang ni's naka air cooling system. need ug maintenance ang rad and its rad fan(s)...

dili lang na sa rpm tan-awon if mamili ug fan para sa rad. Pinaka-importante ang static pressure. If mahimo never settle for any fan with an SP rating of less than 2. Dili kaayo nindot ang review sa Seidon. Mao pud iyang tubes, kung sa akoa lang mas mu prefer ko sa rubberized tubes pareha sa kuhler ug bag-ong H series sa corsair. Sa akoang experience, I had my H100i's rad set as intake. Wala'y abog ang sulod sa case, naa tanan sa rad ga tipok ang abog hehe. In terms of temps issues with rad set as intake, di man pud muinit ang case temp nako. Based sa sensor around 32-36c ang temps inside sa ako case during Intel Burnt Test na. Basta nindot lang ang airflow sa sulod, rad as intake won't be an issue.

^ na, marketing ra na bro oi... ug sa Software simulation... in real world apps, gamay ra kaayo temp difference ana nila kun magamit ug high static pressure then i-compare sa other fan with the same rpm and lower static pressure. dili mana na gako ug difference sila pud... approx nako kay 1 to 2 Deg C ra ang temp difference in actual use then fluctuating pa gyud... sa koa, 1 to 3 Deg C na temp difference is acceptable. mag lisod ug justify ang cost... if 5 Deg C na or more, kani, dako2x na gyud ni...

naa ko study ani before... pero, dili lang the same ug rpm ang ordinary fan na gamit nko na gipares sa stock fan sa Corsair H50... check the link... kanang Corsair SP120 @ 2,350 rpm designed gyud na sya pang rad cooling... 2 Deg C ra gyud ang temp difference nila @ full load... if i'll use an ordinary 2,350 rpm fans in push-pull config in comparison, basin the same lang sila. but sa price, never mind... hehehehe... 3 Deg C ra man gani ang temp difference on the stock H60 rad fan (single) compared to the dual SP120 2,350 rpm in push-pull config. this is my hard evidence why I say na, its just a marketing tool... but, naa'y factor ni sya... kay ang sa Corsair, naka exhaust set-up... mao ni ang catch... hehehe... naa ko plan na study using 2K rpm fans on the same set-up as exhaust... mo palit pa ko... kay akoa ning palitan ug Closed LCS ang entertainment rig man diri pud...

regarding high SP, its not marketing. higher SP suppose to help if ang airflow is BLOCK(like rads,heatsinks,or behind drive cages) mao nang d ma differentiate using same cmf with high sp vs normal sp if free air flowing....

[lloyd_joy]

that's the explanation in theory bro... but i have a hard evidence on it na negligible lang ang temp difference nila. but sa price, dako2x gyud... sige lang, ato nang ma compare once naa na ang ordinary case fan na 2K rpm... wala ko naka kita man gud diri ug 2,350 rpm pud na ordinary case fan... share unya ko diri sa result if naa na...

ang akoa lang, kay ang data na maka support sa atoang claim... ang result in real world application... pero, gi design gyud na na nindot ug air flow ang high pressure fans. wla gyud ko problema ana nya kay it undergoe so much time and effort from its inception, actual design, product qualification, mass production, storage and to its shipment... undergo pud na'g reliability testing bisan fan lang na sila...

kani ai, pang daginot mode... allow me to share...

> Corsair SP120 (2,350 rpm)... designed for radiators: 693 php equivalent
> Cooler Master (2,000 rpm)... designed for chassis: 273 php equivalent

kun mo palit ug duha, 840 php equivalent (@ 420 php each) ang ma save... just for reference kay lain man ang actual price dha...

but kun gusto mo gasto, no worries ra gyud na... wala'y maka buot sa atoang paliton dba?

by the way, kana diay na gigamit nko na PC Cooler F-128 chassis fan (1,650 rpm) sa study kay priced at 175 php equivalent lang na sya diay. when compared to the SP120, priced difference nila kay 518 php each... kun palit ta'g duha, 1,036 php equivalent na... so, dako dba? then ang temp difference nila kay 2 Deg C lang... worth ba ni for an ordinary Juan?
