watercooling and Aircooling

[wolfsid]

Ok for all you people out there that want to know if watercooling is really that much better. I mean do you really want to spend extra money for a few degrees and a little bit less noise... Some people would like to say yes But I think that heatsink if applied property will work just the same as a waterblock... I did a test just to prove You people wrong. I bought a maze 2-1 with 156watt pelter and the danger den cube, nice block by the way but U might need to lap yours just to be safe. ok now the heatsink is a volcano 5 I nice heat sink I bought a supply shop down here in FL, I tell anyone who buys a heatsink to lap them always makes a difference if done right.. Ok back to the test. The system a Asus A7a266 512mb geforce2pro64 and a amd 1.4 oveclocked to 1481 running at 1.9volts stable temp at idle are 39c with heatsink with waterblock its 37c at idle at load the temp on the heatsink are 46c and with the waterblock its 42c the room temp was kept at 70f the hole time.. well I need some replies on this get back to me...

did you use the tec on any of the test?

[Warlord2]

man I hope thats not with a TEC

anyways water cooling is ALOT more quieter thin just a heatsink and fan+you cant put a TEC on with a heatsink


also the mobo you are using has very inacurrit temp reading

a waterblock is supposed to read hotter thin it really is and a heatsink+fan makes the cpu think its cooler thin it realy is

so I would say there is atleast a 7c difference

between load and idle with a waterblock there is only a ~5c change and with heatsink maybe a ~10c

you can also push more watts out of your cpu with watercooling

but if your not a OC freak by all means smack a heatsink on there

I really have done just air cooling to the date, but having less noise will be better. When I finish getting my rig in place (a dual PIII) I'll move into watercooling, just to be more quiet. But that is just a matter of taste.

you might want to take note in your theory here...

if you used a thermal probe touching the core itself (not the one behind the ceramic surrounded by air) that you'd see a much much larger difference in temps. this is due to the fact that the air moving around from the fan on the heatsink actually fools the probe as it is getting air circulation around it. with a waterblock you dont get the air moving around.

once you do use a probe touching the core you'll most likely see the temps are 5C or more below what the in socket one is reporting.

another thing to note is that no watercooling system is the same, as well as HSF's. you could hook up a waterblock without a radiator and just have a big reservoir and get worse temps than a good HSF.

what i will tell you is that my stock HSF from amd on my 1.2 TBird gave me results of 130+ deg F with around 70F room temp. my watercooling rig would give me temps around 95 to 105 F with the same ambient temp, but that is after overclocking it to 1.47 and upping the core to 1.88V.

then, i bought a thermal probe and realized that the temp of 100+ F wasn't right, and actually am getting temps in low 90's (33C). so thinking that was strange, i placed a small fan pointing over the waterblock and sure enough...the MBM (in socket) reading dropped down quite a bit! but the thermal probe temp stayed exactly the same.

sooo....if you're gonna do this comparison, take the fan off your HSF and aim it at the waterblock and THEN compare temps (or just go out and buy a probe to place on the side of the core).

YES THANKS FOR THE INFO I WENT FOR IT AND BOUGHT A PROBE THAT GOES ON TOP OF THE CPU RIGHT NEXT TO THE CORE DON"T THINK THAT U CAN GET A BETTER READING THEN THAT. I WILL REPOST THE RESULTS OF THE TESTS. I ALSO WENT ADHEAD AND BOUGHT THE NEW Z4 Block To See what difference it is to the maze 2-1 with a 156watt pelter i will have the results in a few days waiting on ups,LOL. Blackbox Aka Wolfsid:cool:
