First wc run questions

[eltinio]

I finally got some time to install the last part of my wc setup with is as followed:

Rad: PA 120.3
CPU: DD tdx (old version)
GPU: DD maze 5 (chrome )
Pump: ddc 9w with xpsc restop

The radiator is on the top of the case and the pump is on the middle plate of an lianli v2110, and the loop goes like: pump -> rad -> cpu -> gpu -> pump.
The pump is on the bottom of the loop.

It has to cool the following:
CPU: AMD x2 4800
GPU 3870 toxic

It isn't the best but i's a upgrade to me and I don't need al that much power but I do got some questions.

It was absolute murder to bleed the system en when I finally get it bubble free an without a lot of noise it's fine but when I turn the pc on i makes a lot of noise from air in some places. How can I fix this?

I haven't got a hdd so could only go to the BIOS to check the temps but the CPU was 34 degrees and i was kinda disappointed, the ambient was 25 degrees and there was no difference with fans on max flow or min flow (zalman fan controller). I had expected something below 30 even with these hot ambient temps. Is this an ok temp ore not and what is holding it back? Could it be an bad mount ore the limitations of the old tdx block?

I hear ya about the bubbles but there really isn't much you can do but wait. It could help if you tap your pump a few times before you power on to knock loose some bubbles. But that might not work.

Those temps are a bit high for idle. I think the reason is the old tdx. The old tdx is really best for single core cpus. Since your running a X2 I assume thats the problem. The main improvement in water cooling is your load temps, so if those are really disappointing, then I would say its time for a upgrade. In most cases you wouldn't really don't need a $70 block. From what I've heard most of today's block only have a few degrees difference. So if your low on cash something like a Apogee GT would most likely yield a big difference your you.

paste? nozzle kit? which way is ur tdx mounted?? IHS removal maybe..?

[Lloyd]

Seriously mate, treat yourself and get an EK Supreme or D-Tek Fuzion v2. I'm sure you would be more than happy with the temps.
Even so those temps sound high to me, how much thermal paste did u use?

EDIT: Under air (Zalman CNPS9700-NT nVidia) in a very warm room my X2 5200 is at 52(core1) and 54(core2). Oh and it running wcg and folding@home

[eltinio]

OK, i already thought something like the TDX block being outdated and build for single core.
I'm kind of a DD fan so i probably go for an MC tdx Ore a fuzion v1 or v2.

Pump, cpu, GPU, rad would alllow all air to collect in the rad where you can use the bleed screw in your PA120.3 to remove it.
The way it is now has at least two bubble traps.
No mention of reservoir or T-line. Have either?

[eltinio]

@ RRR: I like the look op the black supreme but i always thought it liked alot of flow and i only have a 9w ddc pump.

@ Jedda: I have a XSPC reservoir top for the ddc pump but no t-line ore so.

I used the bleed screw on the PA120.3 an filled the resevoir up to the top and it seems te be better now. I do see some bubble's come uit of the loop (small ones) but becasue the reservoir inlet is so clase to the pump intake it looks like it's sucking the bubbles right back into the loop.

Is there anything to do about it ore isn't it a big problem?

[Conumdrum]

Do you have a vario pump? If so slow it down and the bubbles will find it easier to flow to the top before being sucked in. Or you can pinch the hose a bit to slow flow for a day or two.

[eltinio]

No vario pump, it's one of the first simpel ddc pumps. But I'm now running silent and bubble free, it only is noise when i first start it i can especially hear the bubbles from the radiator (highest point).

[IanY]

The EK Supreme needs a decent amount head pressure. Its an impingement jet block.

However, anyone who says that only head pressure is important and flow is not needed needs to get their heads checked.

The whole concept behind the DDC-2 Modified Top was to sacrifice some head pressure for more flow. The DDC 3.2 is a pump with weaker head pressure but the concept behind the modified tops is the same. The DDC-1 9W still has decent head pressure. The whole idea behind the D5 Modified Top is to sacrifice some flow for more head pressure.

Both head pressure and flow are needed.

[SeanB]

can you try pump cpu gpu rad, then tell me what temps you get?
also the reseat/paste job may improve it.

[eltinio]

I'll try an reseat of the cpu, I don't think it will make a big difference and i used a piece of copper pipe to get the tube management nice and clean.
