Flow direction on TDX and Temps

Okay I have a TDX on a 754 3200+ @ 2.4ghz. BIX3, tygon, 3 120mm fans sucking air through the radiator to blow out the top of the case.

If I had the inlet tube hooked up to the outlet of the TDX, would that make a huge difference in temps? As you guys know, the TDX's inlet is right over the middle of the block, with the outlet offset on the side. Would starting the flow from the outlet of the TDX cause a huge change in temps?

Reason I'm asking is because my system is at 45*C idle and up to 52*C on load - and I just realized my flow is backwards.. however I'm still wondering if this could be the only reason I'm not idling at 35*C like I should?

Anyone had any similar experiences?
 
It should lower your temps, by how much I am not sure, at least 2C though probably. Are you using an accelerator nozzle on the TDX? If you are it could be clogged resulting in even less flow.
 
The TDX uses impingment to perform well, so improper routing could be the reason your temps are so high. While there are a lot of ways for your loop to not be performing as well as it should be, improper tubing/component routing can be an easy cause. Check your loop while you're at it to make sure the pump outlet is going to your TDX inlet or radiator, and that your T-line/reservoir is right before your pump's inlet (assuming of course you're going to replumb your loop, or at least fix your TDX's routing).
 
Thanks for the reply.

Yes my T-line is before the pump inlet - so I guess I'll just redo all the piping again.. Arg..

I don't mind the work - the problem is that with a T-line as a reservoir, it takes forever to get all the bubbles out.. I have to keep moving my case around every once in a while to get all the trapped air out of the radiator.

Any suggestions on speeding up the process?

You can tilt your case once so that the T-line is the highest point in the system, then the bubbles should work their way out on their own, and you wouldn't have to keep moving the case.
 
Okay - things are a bit better.. still not ideal. Here's what has happened:

After fixing the plumbing and clearing out all bubbles, I turned on the pc and noticed the same temps.. but the "board temps" were lower! Aha! Speed Fan had temp1 as the mobo, temp2 as the cpu, and temp3 as power/aux.

However, the change in plumbing did drop the idle temps (temp2) by 3*C... so now I'm idling around 37*C. Still this is not what I was hoping for..

My system is a brass top TDX with a BIX3 - the pump is a danger den DD D-5.

This system is at 1.55v (just .5v over default) and I'm at 2.4ghz (220x11). I think this system shouldn't have a problem idling the PC at 35*C or a little lower even. Your thoughts?
 
Well, just because your motherboard says that your cpu idles at 37C doesn't mean it is accurate. Motherboard sensors are notorious for being incorrect.
 
Yeppers......... :eek: Most AMD type MoBo's report temps a little on the warmmer side of things................ :cool:
