Thanks Granma!

[OverclockingAddict]

Woohoo! Granma just sent me $300.00 for my SAT scores! She also said it was for helping her talk her boss into putting a website up, and she got a raise because it brought in so many customers. So, tommorow I'm gonna order a cB0 700E! I was looking into prices anyways wondering how I could raise the money for it, and now I can.

My case temp is 47'F. I have an airconditioner ducted to my open case in my desk enclosure with a 131cfm fan blowing the ice cold air at the 3dfx 60mm alpha

[OverclockingAddict]

Still, my watercooling system has trouble with 2 65w TECs, air cooling will not cool the TEC sufficiently.

sad to see your radiator not able to keep up with the block http://discussions.hardwarecentral.com/tongue.gif maybe i will have to put a minimum radiator-size requirment on my blocks......

Go ahead...... lick my BLOCK :D

Well, it's not entirely hot, 30C... I might add another radiator when I get around to it.

[OverclockingAddict]

Oh yeah, the radiator is 15"x5" with 3 90mm fans hooked up... I might add some fans before I add another rad....

[#Rotor]

my 4"x11" keeps the water temp at a steady 26".... are you sure there is not a kink in a pipe somewhere, a radiator that size should perform much better than that

No, no kinks... The radiator is only slighly warm, barely noticeable. Maybe the piping is thick?

[S_Klass]

#Rotor I've been speaking to some radiator ppl and I'm getting the impression that size is not the only factor. Other factors include pipe diameter, fin density, single/double pass, turbulance from pipe design and radiator mass. What is your opinion on the more critical factors among the expanded list?


------------------
-=S_Klass=- I tweak... therefore I am.

[Big Lar]

Hmmmmmm.... Is Granma adopting this week http://discussions.hardwarecentral.com/tongue.gif

------------------
Help me get this Boot outta my azz!!!!

[#Rotor]

they are all factors that will have an affect on performance...
pipe diameter: I found that having a lot of thin pipes in parallel with one another works better than one thick pipe coiled into a shape, the parallel config actually has the water divided up over a much larger volume and surface area, causing the flow-speed to decrease, but not affecting the flow rate, as in volume of water passed.

fin density: YES, the more you have the better, to a point, you need to get the intersect where adding any more fins will decrease the airflow through the rad.

single/double pass: the least important factor, in my opinion, why, what's the use of putting 2 rads on top of one another, the 2nd one gets 2ndhand hot air blown through it.... http://discussions.hardwarecentral.com/smile.gif, it will have more of an affect, if you dT is very high, say 25ºC ambient, while you are trying to cool down boiling water, then a dually will work better than a single,

turbulence from pipe design: I suppose that will help, but proly not as much as with air turbulence in heatsinks..... I would rather look at effective surface area as a more important factor.

radiator mass: now I'm assuming you mean the actual volume of the rad. i.e. how much water it can hold..... that would be a product of some of the above factors, in itself , not very important, I think.

It sounds like you're using an automatic transmission fluid cooler.

I would hope that it could handle the 100watts or so of heat with no effort at all.

Something else is wrong.

I can cool 2 TECs on my BP6 using a similar-sized radiator and the water temp exiting the cooler is only 3F degrees above ambient.

[S_Klass]

ahhh, many thanks #Rotor.. that helped clear up some contradicting statements from several people. http://discussions.hardwarecentral.com/smile.gif

Well, when I added water to the res last night to compensate for evap, I put it in a bowl with 2 cups of ice, let it cool, and scooped the ice out. It dropped the water temp to 26C, I guess by spreading the heat through the cold water. I don't think 30C is entirely hot, just a little warm, but so far no crashes...

[OverclockingAddict]

Oh yeah, #Rotor, didn't you say you were using a battery charger that was rated at 7amps? That might be why, my PSU's put out 10amps each at 12. Each PSU only has 1 TEC hooked up to it, with nothing else.

[#Rotor]

i was using that charger yes, but the pictures where taken with the TEC's running from a 300W(12a) PSU.... i was playing around with every PSU i have here to see what they where capable of....

[Machupo]

Are there any AT PSU's rated at ~14A on 12V? cause i want to hook up my two ICE-71's and then something to load the 5V line to get max amperage to the 12V... anyone? guess i'll just have to get me one of those 12A 300watters for my main power (this antec is a 300watter, but it's only rated at 8A?!?!?!) and then use this 10.5A AT ps i've got hangin' around http://discussions.hardwarecentral.com/biggrin.gif

[OverclockingAddict]

I imagine a 350w would, if you could find one http://discussions.hardwarecentral.com/smile.gif
