What's better with H2o?

[fullinfusion]

What i like to know from you ppL that run water is....... Are your temps better with the fan blowing (pushing) air into the rad or..... Drawing air through the rad ( sucking through)
And with that,.... what is the temperature difference?

 

[Wile E]

My setup does better pushing. I have medium speed fans with triple rads with less restrictive fins, and get 1-3C better temps in push rather than pull. It's not a really huge difference in most cases. The difference is larger with higher speed fans, or rads with more restrictive fins.

 

[p_o_s_pc]

what wile E said..Also you can run them in push pull. Have a fan on the back of the rad pushing and a fan on the front pulling.

Same as P O S PC and Wile E both said. I've got all my fans pushing. Seems to work the best....

I myself found that having the fans blowing was better.... As for push-pull I haven't tried it.
I just upgraded from a single 120 to a 120.2 rad....and a 940 to the 955 runs the same temp but the 955 is running higher clocks at lower volts...... I guess it balances out?....

that could be a part of it. Also some people don't get much of a drop going from a 120.1 to a 120.2 depends on how saturated the water is with heat.

Im just thinking about the dust..... With the fans drawing through the rad and having a fine foam dust filter on the intake side........ What weighs better?

I wouldn't really recommend a filter as it will add more restriction to something that already restricts the air. That is like asking for death of the fans also i could see that hurting your temps. Just go without a filter and clean the rad every month

I changed from Distilled H20 to Fesser one.... It seems thicker and doesn't flow as fast as pure water.....

 

[Wile E]

Do not use filters on rad fans. It kills pressure. Just dust your rads out with a can of air every couple of weeks.

that could also be a reason for the same temps. Also keep in mind the 120.2 rad will slow the flow down alittle more then the 120.1 did. I bet if you put a better pump(higher flow) it would lower your temps

also are you still using the TT pump?

yeah but i clean the filter every 8-10days...... does having a filter really affect temps that bad?

Yes. Don't use filters.

What would you recommend.... keep in mind I wanna keep the noise to a min.

having a filter drops the pressure like wile E said. So yes it can affect the temps alot... its just better to not use a filter at all on a rad no matter how often you clean them.

It recommend the siwfty 350 its quiet and gives good flow also its small

Ok coming from you I hear what your saying

Thats cheap enough.... I booked marked it.... Thanks man!

so I guess I need to break down my rad ass.. and put the fans pushing to the rad.... Sighs.... I dont wanna loose another finger nail

 

[TeXBill]

No filter needed just keep a can of compressed air and blow it out a couple of times a month. Works great for me. I got 4 120mm Scythe Ultra Kaze fans on my rad all pushing 3,000 rpm's a piece. AC is louder than they are.....

The best is push/pull.

Advantage of pushing... plenty of air behind the fan to push through the rad.

Advantage of pulling... no resistance on the air being pushed by the fan.

Do what's best for your setup. Tests say push is best if you can't do push/pull.

 

[phanbuey]

it depends... test it... i have better with pull... some have better with push. General rule is low speed fans better in pull and high speed in push. But test b/c each setup is different.

i have seen no difference with 1400 rpm fans whatsoever... pull tends to be quieter and easier to clean.

Ok with that,,,,, what 120mm fans should I order for a push pull 120.2 settup?
Keep in mind, I want the best flow and performance with minimal noise.

 

[TeXBill]

Take a look at these nice rpm and not to loud..

They should move enough air for you.

 

[Binge]

The best low noise fans that rock performance are the Scythe Gentile Typhoons.

We went over that in another thread. Everyone's setup is different, and responds differently to whether the fan is pushing or pulling. That's why I mentioned so many details about my setup. Push almost always works better on my rads.
