High Temps

[chrisf.uk]

hi

Im currently running -

e6300 @ 3.4 ghz - 7 x 486 (1944) 1.325 set in bios giving me 1.33 underload (vdroop mod)
P5N-E Sli

DDC 1 with plexi top
Thermochill PA 120.2 with 2x yate loons at 7v pulling air from top of case
Apogee
maze 4 on 7800 gt
7/16 tubing

Im seeing 35 idle for both cores and 58c load , sometimes up to 61 ish.
I have remounted the block several times to no effect . cpu is lapped , that gained me like 2c.
Temps same on both cortemp and speedfan latest versions.Asus probe shows 10c lower , presuming thats measuring socket temp not core temp ?

Am i missing something here , these temps seem way high for half decent water cooling ?

Is your Apogee the "GT" model? have you already tried running your fans at the full12v speed? This might gain you 2-4c drop.

[Grinch]

what's your ambient temp?

[chrisf.uk]

thanks for the response

Putting the fans on 12v gives me 56c load , so 2c drop
will post back shortly with ambient temps when i get temp monitor off a friend

see anything wrong ?

cheers

Try it without the fan on the NB - quite possible it's recirculating hot air off the back of the GPU and the NB itself over the CPU (IHS edges - which do count) and mosfets and other local heat transfer pathways in the vicinity of the CPU.

Other than that, if you've ruled out mount and IHS (via lapping)... a huge airlock in the rad. What happens when you turn the PC upside down (stand it on it's head with the PC switched off so pump isn't running)? If a pile of air comes out of the rad - that's your main problem.

i've got a little digital thermometer on my wall that i use for ambient temps - works good :)

[chrisf.uk]

Ambient temps are 26c
I have turned the north bridge fan off as you said , that doesn't do a thing to cpu temps.
Little bit of air was in the rad , 2 small bubbles, no change :confused:
Bad ihs contact with the core im now thinking :(

thanks for the response

Before you go popping the IHS on your proc, try running the rad outside of your case. it looks like half of it is blocked by your optical drives. and those fans are blowing down on it? Maybe flip em over?

Post some pictures of the IHS and waterblock when you try to remount it.

with an ambient of 26c, those temps are AWESOME!!! there is nothing wrong with your rig... you need an air conditioner!!!

hi , the fans are pushing air out the top of the case, there is about 40mm between the rad and that optical drive and it only covers like half of the rad , i did try placing another 120 under and it didn't seem to do anything for temps.

i had this same setup apart from the apogee , had storm on a x2 3800 @ 3 gig with 1.37 volt and under load it was 43-45 with the everything the same.
Temps just seem high to me :confused:

thanks for the response

[Bail_w]

x2 3800 and E6300 are totally different CPU. besides, Amd run cooler than C2D.

I had a set-up like this before. I think you will see a big improvement if you reverse the radiator fans to suck the cold air into the case. When I had the hot case air push out (thought it would assist convection) through the rad, my CPU temps were a lot higher. This was in a cramped Wavemaster case and your case reminded me of it.

Also, do you have the front and back 120mmm fans pushing air into the case right now? You should have the case fans feeding in air from the outside and the rad would push it out the top.

Obviously, if you reverse the rad fans, have the case fans draw out air to keep everything balanced.

[Bail_w]

push/pull no differences in temperature, because i already tired.

[Grinch]

+1 for pulling cold air into rad

[Sh0ckwave]

Yeah those temps are too high for sure. for reference my E6400 @ 3400mhz 1.45v doesn't go over 55c with an air cooler...

[RockfordFosgate]

My ambient temp 28 C

E6400@3.0 1.35v

Tat

Idle 37 37 or sometime 35-36

Load 41-41 (ortos)

my ıdle temps are too hıgh :(:(:(:(

[chrisf.uk]

Something i have noticed with my setup -

Current idle 36c for both cores
Put prime on small ffts , jumps straight to 52c and then climbs from there upto 58c :(

[Varsos]

I think this is normal cause your temperature in the case is raising when priming so every minute that goes by your PA is sucking hotter and hotter air.
I also vote you push or pull air from OUTSIDE your case.

I recently came across the same problem with my setup. When I first set it up I had load temps in the mid 40s then one day I start seeing 60s+ and I remounted (a lot) and rebuilt my loop but still can't get temps back under 50.
Sorry I can't help but I wouldn't mind knowing a few things from this thread too.

[Bail_w]

In my case, i have a Lian li 1000 case where my fans are inside of my case pushing air out and the system temp is at 30s. if i have the fans pulling air in my system temp will rise up to 40s. Therefore, pushing air out for me is better.

[Friedchicken]

Try having that rear fan push air into the case. I suspect that your board is heating the air you are trying to cool your rad with.

[Jedda]

Could you test by temporarily removing that drive and placing a cardboard screen below the rad, so it creates a duct through the open drive slot?
Cut off the inner case air and see what your temps do?

[chrisf.uk]

hi
the case sides are off , the inside case temp is the same as the room temp , so surely altering fan directions etc wouldn't do anything ?

Im thinking its a contact problem with the way the temps shoot straight up underload.
Im going to strip the cpu block over the weekend to see if its a GT or not as im not 100% sure , if not i will lap it as it doesn't look in the best condition as it was 2nd hand.
If i have no joy with this then i will try changing rad fan directions etc , this is a last resort as the top of the case needs to be removed :(

thanks for all the help :up:

[Friedchicken]

with the sides off, you still have the heated air from the motherboard rising straight into your rad. Plus, a bad lapping job will worsen your temps.

[chrisf.uk]

Hi

It turns out that the cpu block was just a normal apogee , i lapped that to 1200 as the centre of the block was lower than the sides , that gained me 1c :( , i did also test my storm and that was 7c higher than the apogee lol .
I have tested fan directions on the rad and case fans etc , temps no better.

Having looked through various threads and sites it looks like its the ihs contact to the core:mad: as it jumps up like 15-20c instantly.

Thanks for all the suggestions , may grow some and take off the ihs ;)
