I still don't understand my temps (coolant temp?)

post #1 of 17
Thread Starter 
I just picked up a digital aquarium probe thermometer and stuck it down my T line so I can get some accurate water temps. This is what I'm getting:


My deltas are still really small especially with TAT core temps, but it just doesn't seem like I'm pulling much heat from the CPU core. Doesn't seem possible to have two bad core temps, and the fuzion is a good block. I've reseated the block 3 times now and even lapped the processor:


What confuses me the most is how my idle temps are high, but my load temps are good. I would think if the water block/mount wasn't transfering heat well they would both be equally bad or good.

Only thing I can think of is maybe flow rate(I do go up about 1C changing the pump setting from 5 to 3), or maybe there is something wrong/obstructing inside the fuzion. I went ahead an ordered another pump, so I'll try running two loops. I'll also go ahead and pull the fuzion apart at that time.

Anyway, what is an average delta from ambient to coolant temps?

Thanks!
Martin

Where did you put it in the loop?


That is very important.


Sry I didn't look at pics (dial up...)

what is your configuration? i.e. where are your radiators in the loop? one before cpu and one before gpu?..

EDIT: oh i see what your saying now!.. your coolant temp is straight after your cpu & gpu and its 3C delta to ambient!... hmm that is really wierd!...

ooh i have an idea... have you made sure that the copper part of the waterblock is correctly orientated?

My loop goes like this:

MCP655 Pump> MCR320 Rad> MCR320 Rad> D-Tek Fuzion CPU WB> MCW60 GPU WB> T-line > Back to MCP655 Pump

And I have another MCP655 coming, so eventually it would be two loops:

Loop1
MCP655 > MCR320 > D-tek Fuzion > T-line > Back to MCP655

Loop2
MCP655 > MCR320 > MCW60 > T-line > Back to MCP655

hmmm might want to try the 2 rads before the cpu and GPU.
Like rad then CPU then rad then GPU.
Worth a shot.

Yup thats the best way to go, thats what i plan to do.
My second loop will have my GPU,NB and MOFSET, lol.
My lucky CPU gets his 480GTX all by himself!! spilt little s**t

Yeah I figured that can't hurt although I'm still questioning my block/mount. I do notice about 1-2C increase in temps if I lower the pump speed.

I probably really ought to pull the Fuzion apart and look inside (I never did and maybe I've got some gasket gunk all over the pins or something.

The other thing I wonder about is that the Fuzion did not come with a backplate. Maybe I'm just not getting enough pressure on the contact or my MB is warping too much. I guess I could make my own backplate to try.

Maybe, but my guess is on the flow rate,
CPU,GPU,T line 2 MCR320's.....give that 655 a break LOL, he might have a dam heart attack!!!
or pump attack!! lol.
Get another 655 and redo the loop, leave the CPU on its own loop and put the others in the other loop. Try add a NB, a waist if you just have 1 loop for the GPU.

I have in-line temp probes one right before the rad and one right after..Or I did I haven't hooked them back up yet on this loop... ...Anyway I dropped 1.5-2.5C across my rad..A 240 BIX with 2-108cfm Sunon on a 3/4" shroud in pull config....The out-let coolant would almost always be 1C above the room ambient temp.The top compu-nurse is the out-let temp....EDIT: Yeah you need to always clean new blocks they can have an amazing amount of crap in them...

LOL!
Yeah I thought about getting a NB block like the MCW30, but I hope to someday get another 8800 and run two in SLI, so I'm holding back. The thermalright HR05 is doing a good job now anyway, only 35C.

Maybe later I'll get another loop going for that stuff, for now I just want to get my CPU temps down more.
