have i done well on my 1st w/c rig?

slicey · 05-03-2005, 08:45 PM

hi,
after building my 1st rig and getting temp readings for idle/load, i'm left wondering if these #s represent a good effort or not? here's the specs followed by the temps: prescott 3.2 @ stock voltage(this is the only waterblock) the w/c system consists of a 2-302 core, mcp-350 using 90% 1/2" tubing, two 6.75" papst fans drawing about 130cfm through the core, all mounted in an external enclosure. the room temp was 74F, idle was 42C and load was 50C. i thought this is on the high side but i've nothing to compare this to?(read, i don't know jack for w/c experience)

what block are you using?

maxSaleen · 05-03-2005, 09:33 PM

Are you using mb readings? They don't mean jack

We will assume that when you say 90% 1/2" tubing that you have 3/8"->1/2" conversions on the inlet and outlet of the pump. This might actually hurt your performance.

maxSaleen · 05-03-2005, 09:34 PM

Good effort, btw. Could you provide more 411 on the fans?

slicey · 05-03-2005, 11:07 PM

i,m sorry, my block is a polarflo tt. i,m using abit's ABIT EQ for temp readings. boy, i thought i had included all the important info in order to avoid these follow-up questions, sorry. about the fans Max, they are papst 6424/2h, go to www.allelectronics.com to learn more.

nikhsub1 · 05-03-2005, 11:18 PM

Well, at least the Abit Mobo's for Intel read ON DIE, so this means they will report hotter than Asus P4 boards which read dreadfully low. Your temps are closer to reality than most other P4 boards, keep that in mind when idiots say, "Dude, I get 35C load on my Prescott with the stock heatsink at 4.2Ghz and 1.6V, your watercooling must suck".

my tubing goes like so: 1/2" barb on a large, electrical junction box. connected to that is a 10" run of 3/8" tubing to the pump inlet.( i have the part to do the 1/2" inlet mod but a little weary about doing it, even with access to a mill) another 10" run of 3/8" tubing from pump outlet to the core's 1/2" barb. then it's nothing but 1/2" tubing from the core to the block, through the included Y-fitting for a single run back to the reservoir through one more 1/2" barb. BTW, all barbs are brass and are bored out a little and the inlets or outlets are bevelled depending on where each is in the loop.

slicey · 05-04-2005, 12:05 AM

i thought i would add an interesting tidbit. originally, the inlet tubing was and still is 1/8" thick walled but the outlet tubing was 1/16" thick walled because i was worried about clamp clearance, but that tubing was smashed, like it was near the end of the roll-which it was-this seemed very restrictive so i replaced the thin walled stuff with the thick walled tubing and used my beloved zip ties. the interesting part is that before the swap the idle temp was 38C and load was 48C i believe. maybe i did a bad mount job and/or TIM application? i just don't know at this point, unless of course, i want to attempt another remount; uggghhh! any thoughts/

MadHacker · 05-04-2005, 01:29 AM

I have an ABIT IC7Max3 board.
also have a 3.2 Ghz Processor... it runs at 54C
that would be motherboard monitor that is recording it...
that is at full load... don't have a tempurature of not under load cause i'm always folding.
it is watercooled with a WW,
as for pumps and heatercores look here
mind you I use that rad box to cool 2 PC's
but as nikhsub1 said the temperatures aren't realy valid...
they are good to do self comparisons.. for changes on your own system but even same model of MB will give you diffrent temperatures.

I read somewhere that with Abit boards, the real temperatures are closer to 10-12 degrees lower then reported...
but I also read that the moon was made out of cream cheeze one time... :shrug:
<edit> have any pictures?

Prescott 3.2, still at 3.2 GHz?
The exact temps reported from ABIT EQ shouldn´t be trusted, but the 8 degree difference between idle and load are a little bit more accurate (not absolutetly accurate, but better than the reported temps), and 8 degrees isn´t too shabby on a Prescott.
Did You check the temps with aircooling? If so, compare the idle/load diff on air and water.

Again, the Abit's read the CPU's on die temp sensor, they read higher than other boards but they are also closer to real than other boards. MadHacker, the real temps are NOT 10-12 degress lower than reported, they are actually hotter in the center of the core, the P4's have 2 on die temp sensors, one that is used for thermal throttling and shutdown which we can't access (more in center of core), and one off to the side of the core close to the surface which is the one we can read (AFAIK Abit and DFI are the only 2 that use this) and is likely 15C cooler than the thermal throttling zone.

I had it overclocked to 3.8Ghz for a while but then i got a bluescreen on boot up...
so i set it back to stock. havn't had the time to go through and overclock it again...
Sorry I never ran my CPU air cooled.... and since it is folding all the time it is never idle... so i don't know idle temperatures.

Well i stand corrected...
does that mean the moon isn't made of cream cheeze either?

Chew_Toy · 05-04-2005, 01:44 PM

I agree with NS1 that the Max reads close to real as any I have seen (even tho I dont know of any that you could call accurate).
The 10~15° lower than actual fidure came from a test done by the bleeding edge site and was the difference they saw compared to thier proble which was paced in the stock HS 1/16" above the IHS. With the reading coming from a probe in the actual HS it was probably repeatable but would always read low.

The article has been taken down but here is a Post that has most of the results listed. I can easily believe that thier probe to be arleast 15° low from actual.

Here is a shot I took of my MBM% hi/lo readings for the last few days with my 2.4c on my IC7 Max3 with the average ambient in the mid to low 60sf and 69° when the shot was taken. I know when my room temp is in the low to mid 70s (normal summertime temps) my cpu averages temps in the high 40sC and my prescott read about 8° higher.

I hope this info helps.

slicey · 05-04-2005, 10:10 PM

what is my o/c ing potential do you guys think? my other components that should help me o/c well are an antec true control 550 and ocz pc3200 plantinum edition rev. 2
i know this should be another thread but you guy are already tuned into situation by knowing what my gear is already and i suck at typing.

El]v[0IsEv1L · 05-04-2005, 10:14 PM

Wow...

So Cathar's best block is the Storm G5 right? Just googled it after I saw your sig nikhsub1.

Looks like a good block for straight watercooling.
