@Doom
so that mean, all heat sink like that zalman shud be place like this?

|| OO11
|| OO11

|| = rear fan
O = heatsink
1 = heatsink fan

and what about stock heatsink?
it blow air toward the heatsink right?
i have a cm hyper L3. it have 3 heat pipes IIRC.
so that means, it suck hot air from the heat pipes right?
and if i have a sidepanel fan. should it be exhaust to suck out the air from cpu or rear fan is already enough for the job.

tq

yah ,,,, best combination and straight forward and less changes in airflow ..

Heat pipe transfer heat from the hot source to the cool area.. which usually is attached with the cooling fins. From there u CPU fan blow away the heat from the fins and let the PSU and rear case fan to suck it out from the case ....

you just need a nice 12cm rear case fan or dual 8cm with the PSU fan to suck all the hot air out ... if u are heat sink that blow air toward it u can equipt it with the side panel that take cool air and faced toward the heat sink .,,,

okeh. got it!.
thx alot mista doom

no problem .. .we are here to share and gain experience ...

i also learn from others here...

My friend went to buy vizo windstorm on wednesday at lowyat ( i told him not to buy because it is too noisy but he still buy..hehe) and finally at night he went and tested the fan..... it is so fast and the fan burned itself.....thank god today he went to replace it.....

maybe the fan got short circuit. drawing excessive current.

hmm .. i thought all these fans have gone through the QC process to make sure at least it works ,,,

anyway that's the only choice in local market for high CFM at affordable price ..

Will there be any wrong if is switch the top fan from exhaust into intake?I mean is that way going to influence the temperature?

I would prefer to have intake for top as it could cool off the ram area before being pull to the CPU heatsink area ....

Dont worry about changing the top to intake ... it woul be more positive effect than negative..

hm.. the hot air is flowing up but u wanna make the top for intake? hm.. sounds not really good idea unless u got a powerful 200cfm rear fan that suck the hot air out

the best way is too do a trial & error test, see which setup produce the best result

some say the top fan is best for intake & some say its for exhaust...

just a bit tiring la, have to remount the fan again & again & again...

but when u got the best result of it, u will using the setup like FOREVER

So, the way that i would know would be changing the position and check the temperature?I will change it to exhaust and see as my current LL front and rear isnt performing up to expectation.Silent but bad preasure...Need to change the front to Noctua and rear to SS..

huhu...2 Noctua as front intake? coz see you wanna order 2 Noctua fan at irangan bulk there... me too wanna get 2 Noctua fan as intake...already have Silverstone FM-121 at rear...wanna see how much it can help for my case air flow...

Nah, not really.Might keep it when i needed another front intake or maybe convert it to a side intake if i am going to get myself a side panel for LL. For now, i am planning to get a Noctua as front intake and a SS FM121 as the rear. Already have the SS FM82 as top exhaust. But i am surely running those SS fan at merely half of their speed as its really too noisy to my liking.Hopefully even at half speed, its still able to provide me a good cooling solution and air flow...

The reason i say to make it intake for the top blow hole ... becoz the cool air goes down and mix would be pull to the CPU area and exhaust by both the rear case fan and PSU fan ....

it is a pull configuration whereby dual 12cm pull VS single 8cm push ..

obvisouly the air hot air from PSU wont really rise to the PSU so much as compare to exhaust by the rear case fan which always speen at higher RPM to push hot air out from the case ...

at half speed (1200rpm) you will hardly heard any sound from it... but the air flow is not that great... from my testing just now... the noise level for 1200rpm and 1600rpm is not much different but the air flow will be a bit bigger for 1600rpm...so you can try play around at that level... not necessary to run it at half speed as I notice the temp will higher 1-3C in my case if I turn it to 1200rpm...which is not so good for my Pentium D...maybe during cold weather can turn it to half speed or even below 1000rpm... maybe for your casing will be different from mine lor coz you are using LL casing now... and you have FM82 as top exhaust...I only have FM-121 as rear exhaust...

Ok, guys..

As recommended, i did change the top fan (FM82) in my case from intake to exhaust just now.After about 1 hour+ in a closed room (door closed, only a single window is opened), i am starting to sweat.lol...Then, when i checked with PC Wizard regarding the temperature, it has risen to a crazy 53c on idle. As far as i could remember from my C5 days, it will barely touch the 50c mark..

Then, i changed back to intake and currently, the temperature is about 45c. What might be the problem here?

I tried to experiment myself regarding this problem and found out a few possibilty.

Could this be the problem of using those silent but poor LL case fan as front intake and exhaust causing the air intake to be poor?I mean, those fan are really really poor.I could barely feel the air when i put my hands near those fans..

And not to mention, the LL case came together with fan filters. Would these filters be blocking the air flow of the case?

Now, i guess i desperately need to get myself the SS and Noctua to get better airflow if the fans are the problems..

Ok.Thanks for the info there..I just realise about something here.When i changed the position of my FM82 from intake to exhaust, the noise level was actually lower even at full speed.When it was as an exhaust, the noise level was tolerable with me but when it was as an intake, man, its almost unbearable.Too noisy there..Thats why i was running it at 1/2 speed.In this case, if the FM121 wasnt that noisy, i could tolerate it running at full speed though...

I think the temp will drop to 45C when you put the FM82 as intake is because the cool air will directly go thru your Zalman CPU cooler there (in case the top blow hole is at the top of processor area there) and then exhaust thru the rear exhaust and PSU fan... when you put the FM82 as exhaust, the cool air from the front intake is not enough to cool down the whole case as it will pass thru hdd then go up, then will exhaust at rear exhasut, PSU fan and FM82, so the air flow is a bit messy inside your casing because your rear exhaust fan is not storng enough...

If you change your rear fan to FM-121, and your front intake to Noctua fan, then the condtion maybe different a bit...coz the FM-121 will be strong enough to push out the hot air and the Noctua fan will bring enough cool air in too... so, the hot air at the top near the PSU and cable there will be able to exhaust by the FM82...

Anyway, this is just my opinion and estimation...I might be wrong...so please correct me if I am wrong so that I can learn too... me too still trying to make my rig cooler...

make sure u change the rear fan mesh filter to those ring type ones. air can flow easier. the front filter is up to u. i changed mine to uglyvamps's filter. the default LL filter has holes that are just to big to be a filter. if u ditch the filter, u get better airflow. but dust.............

Great idea here.I will definitely try this out when i get my hands on two good fans for my front intake and exhaust.I am still considering something more silent but pushes enough air as well..

Well, the fan filter mesh that came with my PC-7 have really tiny holes.I am not sure what other filter does LL have by mine as like an aluminium plate which has really small holes. And my best guess is that these tiny holes are somewhat blocking the airflow of my already poor LL fan.I am inclined to take out the filters as dust is a really big problem to me..Now, i need to search for a better fan as well as a better filter..
