Do these temps seem normal?

[dp152]

Just built this new computer complete with a Water Cooling Setup, partly from DD, and partly from Dtek. My temps aren't as low as I expected them to be, though. They are only a few degrees lower than my Volcano 7 setup on my other computer. Here's what I have though:

Maze 3
Eheim 1250
Bayres
The Dtek RAD (cant remember the name)
Delta 120mm
Tygon Tubing
Water/Water Wetter mix

Cooling:

T-bred 2400+
Not overclocked

With the flow:

Pump - CPU - Rad - Bayres - Pump

My temps at idle is anywhere from 40-42* C. That's with the Delta on low speed I'm lucky to hit 39* C when the fan is on high.

During gaming, with the fan on high (always), I hit 43-45* C.

Is this normal? I have enough airflow, and I used to have two Delta's, but the temps didnt differ at all.

What can I do to lower the temps? Could I use the stuff cars use in their A/C systems to cool?

I just want my temps to go down so I can overclock. What can I do?

I get those same temps with my stock HSF... only on a 2000+XP, but still.

I don't know much about watercooling, but here's what I would do.

What you might want to do is grab a thermometer and stick it in your resivoir after gaming for a while. Find out the temp of the water. This will tell you that either the WC setup itself is hot, or if your waterblock is not doing it's job. If your water is close to the temp that your CPU is, then you know it's because you aren't cooling the water enough. Remember that it still helps to cool the res when you WC, because once the water heats to the temp that your CPU is, it won't do much to bring the temp down.

What are the temps of the case in comparison to the CPU?

First off, I am gonna assume your not new to setting up computers since you put together a watercooler. I personally think a delta of 6C is pretty awesome, but I don't know if its your motherboard compressing the thermal diode's reading or if you just have a really great cooler. Motherboard manufacturers tweak the readings from diodes (internal or external) to read what they want them to. Some try to be more honest and some don't. If you have the exact same mobo in both your setups then you can compare readings, but know also if your readings are coming from a socket thermistor, the wind of a fan on top of a heatsink will cool that air in the socket and confuse your accuracy. Since there is no fan on a waterblock (at least most don't), that will never be factored into the temp reading.

On my watercooler(was running a 1ghz T-bird at 1.4ghz @ 2.0vcore ~ 100watts), my idle temp was about 2-3C over my system temp (as measured my mobo's thermistors and a side core thermistor). I had a delta from idle to full load of ~12-13C, so your delta of 6C is dang good.

Is it really warm in your room, (I ask because your idle of 39C is pretty extreme). What is your system temp and room temp?

Seems a bit high to me for watercooling, but I don't know anything about it.

I get better temps than that with my SLK800a and a 1600+ overclocked to 1817mhz

Room stays fairly cool. I'm pretty sure the temps are correct, though, because both my mobo reading and my Motherboard Monitor readings are exactly the same.

Could it be possible that the pump is heating up the water before it goes to the block? When I feel the pump, it is quite warm. I'll check the water temp. and see if changing how the water flows will help.

Could I use freon in this system? Or would it cause problems? Its the stuff cars use in their system, which is set up much like a WC kit in a computer, so I dont see why I couldnt.

Just reapplied AS3 and changed the flow direction to:

Res - Pump - Rad - CPU - Res

Temps are just the same. What can I do?!

Would something like Anti-freeze hurt the system?

 

[WarCon]

No, but it won't help the temps. If anything it will hinder them. Anti-freeze should only be added if you're not using any other anti-algae/anti-corrosion additivie (like Redline's Water Wetter, which is what I would suggest).

I think you should put the Volcano on this system and check temps. See if your watercooler really isn't up to snuff or if this setup is just reading different than you're use to. But thats up to you, (I would of if I thought my watercooler was underperforming badly). I would also overclock to max stability point of the heatsink and of the watercooler to see if the watercooler was worth the investment, but that is just me. I do stuff like that.

Bump.

Any other suggestions?
