1090T water cooled temps

[blair]

Hi,

My 1090T is OC to 4Ghz at 1.46v at load and gets to 55C load after 30 mins and at idle at 1.43v its 36C

I have two apache fans blowing air through the rad and thats it its a 360 rad but because of my case i can only have two fans blowing through. Ambient is around 18-22C.

Using MX-4 TIM

Is that about right or is it high?

Rest of the components are the XSPC Rasa 750 kit.

I'm almost able to answer your question. I've calculatle the heat load to be 174.89W. Your water temperature is ~23 to~ 27C(give or take .05C). I've contacted XSPC as to the performance of their waterblock. I need to know the C/W of the waterblock to fully answer your question. Hopefully, XSPC gets back to me soon. In the meantime, it sounds like your fans are too slow.

Edit: definitely get faster fans.

the fans shift

Max airflow 57.53 CFM (97.74 m3/h)

Max static air pressure 2.64 mm H2O

I dont mind the temps as they are fine as i like the quiet operation of it i cant hear the cpu cooling at all.

I know if i had push pull i would get better temps and if i had 3 fans on the rad not two and i am also blowing air out the case if i sucked it in would drop a few C as well.

I just wanted to know if the current temps reflect how i have this set up to see if maybe the block isnt seated properly or something like that. Not interested in increasing performance by adding or changing anything if you know what i mean.

Thanks for ur help.

hmm I idle at 22c at 1.425 and load at 35c with my d-14 ambient of 25.5c

what OC does yours have?

what OC does yours have?

4Ghz can get 4.2 with 1.45 but its not 100% stable lol will crash at the end of benches lol right as its about to give score lol havent taken the time to get it stable at 4.2GHz lol being lazy. Most of the time when I have the time to OC I have my 3 and 5 y.o. and they drive me nuts while I'm trying so I lose patients. I'm off this sunday for a change and they will be back at thier mums so maybe I'll play with it some. Give ya some better oc's to compare to.

lol

bump?

 

[JesseLactin]

Totally didn't realise you had 2 fans... no posting until after my first coffee. Your actually dissipating ~187 W. Given that, your temps are normal (probably-I got nothing to compare to ). Also, how does S_I_N idle below ambient?  May end up writing temp calculator after all. Edit: spot on after all. actually , the mx-4 compensated for a missing fan. lol

Thats too high dude tbh a D14 would be cooler than that. Id double check everything and also make sure the pump is being powered from a molex correctly.

I can see that the fans that are internal are not flush to the rad with a massive gap letting probably 80-90% of airflow to be lost, its pretty much acting as a passive cooler.

Thats would be my first priority to change.

Edit, seeing as this looks like a low FPI rad it wouldn't be as bad as i thought although my point still stand, i can put my paint skills to work and show you the general problem.

And of course check the pump and if you like the cpu paste.

 

[JesseLactin]

if tom is wrong, double check the TIM. you loop has a c/w three times worse than a NH D14(.0500 vs. .1746). I'm guessing that is where your problem is. Is it possible for you to check you water temps? Otherwise it could only your fan setup.

Have redone my WC set up now with a haf x case and a 1x 360 rad with 3x apache fans pulling air through it and a 120 rad with 1x apache fan pulling air through it.

I have also added my hd 5870 into the loop and now my 1090T is at 32C idle and the gpu is 27C idle, CPU 54C load and the GPU is 40C load that each one tested individually if i stress both all temps increase by a few C.

Ambient is around 15-20c cant tell exactly as have no way to measure it.

Are these respectable temperatures?

Those temperatures sound fine. The CPU load is a little high, I think mine runs at about 45C but that is in a single loop with a quad radiator so it's probably the graphics chip heating it up.
