Weird Temps with new water cooling set up... ideas?

[^RX^]

Ok peps..... just finished off my new water cooling rig and having some weird temps.....

Cooling:
DD Maze 2
HWLabs Black ICE
Eheim 1048 pump (317gph)
Sunon 108cfm 120mm FAN

Hardware (thats important):
TBird 1400 @ 1605 @ 1.85volts
Abit KT7A-RAID
Good 300watt PSU

Now my room is currently sitting at about 17 - 18c.... my so called idel temps are 35c (mbm5.09) and my full load temps are 39c (mbm5.09) Now i have tried re seating the block etc etc etc.... Air comming out of the radiator is 2 - 3c warmer then going in.... and if the block wasn't seated properally the full load temps should be a lot higher at more then 90watts of heat...

Any ideas people?!?!

Cheers,

have you tried different software to monitor your temps?? I would have to atleast try some others to confirm those are really your temps. On another note I thought with a AMD your size it is best to run with a 400W PSU.

Just tried it with Via Hardware monitor as well.... same temp load and idel.....

PSU isn't the problem with the temp..... thats another issue :D

Those temps to seem to be right to me. Its been proven that water can only cool a little bit better than air coolers. Your cpu puts outs extreme amounts of heat because first things its a athlon running at 1600+ and second you have 1.85 volts. You should be happy to have temps below 40c under load. If you want to achieve lower temps you will need something like a 172watt pelt on there too.

Agreed...... the load temp is really nice for 90+ watts of heat..... BUT the idel temp seems ****ed up...... when ideling its only putting out like 30watts (or so) of heat.... so it should be lower.... eh! who knows.... lol :D

Mek, is right. Those temps sound fine to me. One advantage of watercooling is that you should have very stable temps. Whereas, with standard heatsinks you'll get dramatic changes in temperature; watercooling keeps everything within a nice tight range.

The reason you idle temps aren't much better is your water has stabilized at around 36 degrees centigrade. That is the peak efficiency of your system as it stands. If you want better you'll need to add either more airflow or a bigger radiator.

also take into consideration that if you're using the mb's temp probe, it tends to read higher with watercooling because there's no airflow around the waterblock/socket. i tested this theory with my dd maze 2 setup and noted a substantial temp difference by aiming a fan at the waterblock (been a while, but i think it was well over 10 deg F).

so, since the probe is actually measureing the temperature of the BACK of the cpu...along with being in contact with the air around it, your old HSF actually can lower the PROBE'S temp due to the airflow that cools the air around the temp probe without actually cooling the CORE.

one other thing is that by adding a reservoir you could potentially delay the rise in temperature due to the fact that you have a lot more cool water to start with.
