HELP! My temps suck!

[Sniperboy]

I just got my watercooling system installed, and my temps suck. MBM5 reads 58C at full load and 48 at idle. These are worse temps than with my HHC-001! My system is fully bled, waterblock cranked down evenly, AS3 applied, etc. Here's my setup:
Aquastealth Jagged Edge Waterblock
Aquastealth Northbridge block
Maxijet 1000
Chevette heatercore
Delta 120mm fan at 7v
PVC 3/8" tubing

The order goes pump>heatercore>cpu block>northbridge block

I think one problem might be that my fan shroud doesn't cover the entire heatercore. I had to cut it so that the fan angles at a 45 degree angle. would that kill airflow? Should I make a modified a shroud so airflow is still straight but the fan is to one side?

I'm running an AMD XP2000+ at stock speed.

do you have a way to determine your water temp? Also, try running your delta 120 mm at 12 V and see if that helps.

I think I'm gonna get a Radioshack temp reader to read water temp... good idea. I'll try running the fan at 12v, too.

it does sound like the waterblock isnt level or isnt tight enough, i had the same problems when it wasnt tight enough

My springs are almost completely compressed.

compress them completely

Check and make sure the waterblock is making complete contact with the cpu. Also, get rid of the northbridge block, it may help your temps a little and there is no need to watercool the northbridge, it dosen't really get that hot.

How do I make sure my block is level? I'm not sure.

How do I make sure my block is level? I'm not sure.

Take the mobo out of the case and look at the CPU. You shouldn't be able to see any light shining through over the CPU, just around it.

damn i did not like my temps but ur temps are crap hehe hope u get them down

Once before I had temps like that come to find out I didnt have enough juice flowing through my system make sure your stuff is topped off.

Ok, I have a radioshack thermometer and I put the probe through my fill tube, which is between my radiator and waterblock.
Ambient:24.6C
Water: 26.9C

My system is completely filled. I did put some food coloring in, but was the gel kind and never came out of the heatercore. I'm comtemplating draining the system and cleaning it.

 

[Sniperboy]

Oh yeah, here's my temps with my delta 120mm at 12 volts
Idle: 44
Load: 51
Water at load: 28.3
They're better, but I think I can do even better. This fan is loud at full power! I'll probably get a potentiometer for it.

I'm thinking about taking the plasic cover off the thermometer probe and getting a cpu reading. I wanna see some real temps. Do you guys think I should?

I'm gonna go check to see if my waterblock is seated properly.

Compress the block all the way down, and make some sort of a shroud/duct (you can use cardboard for this) so that way there is no dead spot or any other fan related problems.

That should help your temps greatly.

 

[Sniperboy]

I'm gonna make a new duct that will work better this time!

 

[Nico3k]

what i did to make the block even is that i twisted the nuts down one turn at a time. so i twist the first 2 once, then the other two once... until the block is nice and snug.

Update: My temps are now 46C at load! I'm modding my Radioshack thermometer to read cpu temps now, cause the sensor is too big (it's covered by plastic). Are my temps reasonable now? I'm still running at stock speed.
