hi all.

First off let me say that there are plenty of hyperlinks in this post to help you help me .

Let me make one thing clear: i have only one machine, Umbra, and its that which the water cooling setup is in

Anyway, lets get started:

i run a QX6700, overclocked to 3.55GHz @ (so far, stable) 1.48v

a quick flight on Flight simulator X (with acceleration + VFR Scenery Gen X) has peaked my temps over 75C. (although performance has been fantastic )

i had these temps under air (Thermaltake Maxorb cooler *clicky*) while overclocked to 3GHz - on stock voltages...it was this that made me do the change to Water.

Below ive hyperlinked the more unfamiliar components of my setup, so do click them if you don't recognize the name(s)

My water cooling setup includes:


Dtek Fuzion CPU block (QX6700)

Dtek Fuzion GPU block (2900xt 1GB. overclocked)

12V Laing D5 Vario Pump

XSPC Bay Reservoir - Black

ThermoChill PA120.2 Radiator

S120B.2 Radiator Shroud, 2 Nexus fans & 2 NG120.2
Additional self-adhesive Neoprene Gaskets (2 for either side of fans) (all three on same page)


The water is certainly shifting the heat. that radiator is so hot you just cannot touch it, seriously. it heats my entire room incredibly well, so much so that i have to sit half-naked while playing very processor intensive games. FSX being one of those, i'd actually say its the most demanding game out there.

The enviroment Umbra is ran in is a very clean, somewhat cramped one...see this image. and please feel free to look at my other images.

The entire system is well bled, and fans are cleaned on a regular basis, all are entirely dust-free, especially the radiator and its Nexus fans (linked above). I also use artic silver 5 thermal paste, applied exactly as they describe.

i'm seriously at my wits end. the only solution i can see would be to purchase a Thermochill PA1203 Radiator *click* but this just wont be possible, firstly because i don't have the money, and secondly because i just don't have the room.

Perhaps my problems lie with those Nexus fans, are they any good?. whats the most powerful 120mm fans on the market right now?...yes, noise is an issue for me, but if its possible to get hold of ones which are temp-based then i'd be happy to pay for em.

+Rep to all who help me with my nagging heat problems.

If you need any more information, please check my signature for both images (ensure you look at the latest ones, check dates) and more details, or just ask me here

Thanks alot.

Oh, and don't you dare say take down my overclock

you could have passed the heat load that that radiator can handle- youve got a hot cpu and a hot graphics card on the same loop. If you can, put the graphics back on stock (leave the loop intact, rebuilding is a pain) and see if the radiator still gets super hot. If the radiator stays cool and and the cpu temps are normal without the 2900 in the loop, then Sounds to me like too much heatload.

[edit] I assume you've got the pump on full speed as well, setting 5 is the highest i think. With the fusion blocks you need all the pump power you can get.

As mentioned above your best bet would be to get a bigger rad (360 or even better 480)

The cause of your problem is definitely your rad. If you don't want to spend the money on a new rad than either lower your clocks or remove the GPU from the loop. Between you and I, save yourself some money and get a bigger rad Remember that the purpose of the rad is to transfer the heat from the coolant to the air, the more surface you have for this to occur the better (temp wise).

a 240 rad for both cpu and gpu is insufficient, especially with that 2900, which is a furnace. so ditto what others have said.

Thanks alot for the help guys .

Its what i feared then. i just cannot get a bigger rad. the .3 is just far too big.

Is there any 120mm fans out there better than the Nexus fans i'm currently using?.

I guess i'll have to remove the 2900 from the loop

Edit:

Yeah, i'm running the pump on max speed too.

i notice the Sunon spins at 3100RPM with an airflow of 108CFM

My nexus fans spin at 1000RPM with an airflow of 36.87CFM

Comparing the numbers there is a big difference. but is it a worthwhile investment?

Thanks ^.^

Which way is your air flow through the radiator?

Like the others have mentioned, the RAD is the problem.

American analogy here:

It's like taking a liquid cooled motorcycle radiator and putting it into a 1969 Chevy Chevelle with a 454cu V8 engine...
