A year 2002 article from Delphi says that a pusher fan cools a rad beter than a sucker fan...

why?....

it has something to do with the ideal gas law..... PV=nRT

This law states that in a given volume of gas, the number of molecules depends on its presure and temperature (did i get this right?? my molecular physics aint that good))

Simplifying it...in laymans term ...hot air expands

so in a pusher configuration, the fan works in the cold area where the air is denser with more molecules per volume

and a sucker fan works with slightly hoter air (heated up by the rad) which is less denser and with less molecules per volume.

in the end if you take 2 systems with fans spinning at the same rpm.... the one with a pusher fan will get more air molecules pushed through the rad colecting heat.

get the logics.....?

Since someone asked me about it, I decided to post this (confirmed by aleck as well). Just in case history repeats.

Note:
Inline pumps like the Laing D5, Laing DDC and AquaXtreme 50Z are NON-submersible. DO NOT EVER submerge them into water! This is because they have other electronics at the back of the motor that are not sealed. The word Inline says it all. All Inline pumps should be non-submersible.
Pumps like the Nirox P2800 and Eheim's are encased in a single block of epoxy and thus are fully waterproof and submersible.

Since I tried to be vain and just f***ed up a set of tygons.. lesson learned :

Thin walled tubing sucks, they kink and go soft easily with heat.

Get the thick walled ones.

I recommend minimum 1/8" thick walls for Tygons, i.e. 1/2" ID 3/4" OD, or 7/16" ID 11/16" OD. Any thinner than that and they kink too easily for my taste.

Im about to change my water. Since now I only use the Cooler Master Radiant Mixture.

But recently iI just bought a UV coolent Mixture. Thinking of using other mixture in my system. Does anyone know where to buy the distilled water? or must obtain yourself?

Wrong place to ask. Here's the place to share tip and tricks. Post in the dedicated discussion thread please

i duno where to post my noob question.. so i will post it here since dis thread is for wc tip n trick section..
jz curiuos..
y the coolant in my reservoir de-hydrated so quickly even thought i jz top it up..
is there any prob wif my wc kits ??

You can buy distilled water from 7-eleven. The 5 litre bottle is about RM5. Look for it in the drinking water section as asking the staff will draw blank stares.

could be the problem with the tube as mentioned by some of the forumers and could be also due to the place where u place. find a colder place instead of some place too close to the window.

hi.i want to ask if anyone here tried waterblock + peltier?i want to ask where to find waterblock +peltier in lowyat?which shop sell them?anyone with tips about this might help.thanks in advance...

Hi guys,

I'm new to WC, planning to test out with the Swiftech's beginner's kit at the moment. Just to clarify certain things 1st.

1. For the liquid to be used, best choice is the Distilled water ? Can get those Spritzer Distilled water ? If use with the Hydrx, do it mix it with the distilled water, just 2 caps or pour all in ?

2. For the tubing, as adviced by MetalZone, the thickness should b 1/8" thick, is it easy to bend or twist ? Coz Planning to close back the side panel after installing it. I'm thinking of using the clearflex tubes, good ah ?

3. With a dual 120mm radiator, enuf to cool both CPU and chipset blocks ? I dun think it'll be enuf for VGA to be included together since the VGA are quite hot themselfs. My CPU is E6300 / AMD64 3500+ S939, chipset will be P965 on the DFI P965-S. Better to seperate ?

If my post here is redundant, kindly just remove it, just need to ask some questions, but dun think its a good idea to open a new thread unnecessarily.

Thanks in advance for all the advice.

Jy14, trust me, you don't want to use NB waterblock on Infinity P965-S.

NB waterblock is only best for those Push Pin locking retention.
It's not good for those motherboard that uses Hook retention.

1. I already tried Pure Distilled water myself on my setup. After using for 2-3weeks, there is some white spore appearing in the tubing. I think those are alga ... After that I used HydrX and the problem is solved. As for the mixture rate, you can calculate it like this. 5% of the amount of solution you need. E.g. 50ml for 1litres of water. BUT if possible, dont use HydrX... Its will cloud your tubing quite fast. I just got myself PCIce from uglyvamp

2. The thickness is not that important unless you plan to have a very sharp corner for your setup which is not recommended. Just remember that the thinner the wall, the easier you can bend the tubing. Yeah, Clearflex is a very good option but the price is abit expensive compare to Maskleer.

3. Yeah, a branded dual rad can cool your CPU/NB nicely. But of course the bigger rad, the better If you plan to cool ur GPU too, it is better to do another loop. OR get a good triple rad to cool all of it at one shot; CPU, NB and GPU. But NB cooling isnt that important unless you love to OC with very high FSB else a good NB cooler will do the job. Like what I am doing, I just ordered some stuff from uglyvamp when I visited him in SG. I going to add another GPU block in my loops. So my new setup will be WC CPU and GPU. NB will be still under air as it isnt that hot and real hard to install as need to bend the tubing kaw kaw.

I am not WC Expert. But hope help you abit. hehe.

Would the use of battery water be a good choice for water cooling?

So, does the PCIce can solve the problem of algae and the white spores?

ok, something to ask, do y-fittings got fixed flow directions? i mean as the following pics

well if you want inexpensive solution, get distilled drinking water and add one to two drops of dettol into the resovoir, and let it run for a few cycles and flush it. repeat when u refill the resovoir, and walla, gone is the brown thing/algae sticking onto your tubings...

both method of flow r the same, try turn the 2nd pic 180 degree to right or left...

but i not sure, the y fittings i get seems diff angle at each outlet, 2 same 1 diff, not sure though, need some expert or experienced people explain....
