pls leave ur opinions on what could be wrong.

[litdie]

ok first.
DDmaze 4 cpu
DD zchip
DDmaze 4 gpu
hydor l30
Black Ice Micro II plus 2x80mm case fans. 35cfm each.
clearflex60
hydrx
water wetter.
pump->rad->cpu->chipset->vga->res.

system specs.
amd 2500 at 2.2 gig. 200x11 1.675v
DFI NFII Ultra Infinity
2x256 kingston hyperx
Sapphire 9800 pro
2x80 gig seagate sata raid-0

ok i was running a TR slk-947u and 92mm tornado at half speed and was barely breaking 40C.

i put on my water and im getting 43C max on cpu, 38 on chipset and ,40 on vga.
ambient is 24C or 74.5 F

-at the same time of testing my water-
i was running my other pc same cpu specs and stock cooling. was barely hitting 42C.

im getting good flow and when i feel the radiator it isnt even warm.
also i know the block is making good contact.


any help is greatly appreciated.

I would say its the tiny radiator. A dual 80mm radiator sounds big, but it can easilly be outperformed by a single 120mm radiator with a decent fan. You might want to consider putting some higher CFM fans on that radiator, but I doubt it will help much. The heat put into the system by the CPU and GPU, not to mention the northbridge chip is more than likely pushing that radiator to its limit.

All things being equal, it is most likely the radiator thats giving you higer temps. This is assuming your tubing isnt crimped and you are giving the radiator nice cool outside air, etc...

[litdie]

im gonna put 2 more fans on it and do a push-pull kinda deal.

if the temps drop then im getting a j-120 probably.

the hose isnt kinked anywhere.

[OneMadPoptart]

Push/Pull setups don't really increce performance, but adding higher CFM fans would, but probably not too mcuh. What I am saying is your radiator simply can not handle the heat, no matter how much airflow you get on there.

I would consider a dual 120mm heatercore if you have a place to put it. They are rather big, but they would no doubt bring your temps to a more acceptable level Check out the dangerden double heatercore at http://www.dangerden.com/mall/Radiators/heatercore.asp. For 35$ thats not a bad deal considering thats the same price as the JR-120. You do have to get 2 120mm fans though... Still a nice deal.

Maybe somebody else can confirm the radiator as the reason for high temps before you go buying another radiator.

[joemac]

It might be the radiator. :shrug:
Post a pic of your rig if you can that almost always helps more than product description and layout in situations like this.

[litdie]

the link is now in my siggy.

weird thing is this.

my radiator isnt even warm.

i mean i can look dead at the resevoir and see its circulating, so i know the flow is good.

i just cant figure out why its so hot.

[pHaestus]

slk947u has a design where a lot of the fan's air goes directly down to the socket area. This can cool off vrms and other hot little bits around socket and it certainly moves air around and artificially cools thermistors in sockets. Try pointing a case fan at cpu area.

Oh and your rad's too small too

[pHaestus]

Another thought: Are you certain that there's no air in the radiator? If you are mounting it in the front of a case sideways then that can cause a problem.

[BillA]

1) ck what pHaestus suggested, air in a rad KILLS the performance
2) the rad is NOT too small (and everyone who said so is ignorant of the facts)
3) you need more air, the static pressure rating of your fans is too low
4) do not push-pull, waste of money; ONE fan of the appropriate capacity is far more effective, silent, and less costly

the cooler you want to be, the more air you need to push

I presume you are moving outside air across the rad

[pHaestus]

These fans look like a good choice for 80mm rads

[litdie]

u can see in the pic.


my radiator is vertical.
no air even possible as the barbs are at the top and air rises.

im running 2x80mm case fans pulling air from inside my case out.

the side panel is off my case so that wont make a difference.

after adding fans to my setup it did absolutely nothing.

so i added two 80x38mm tornado fans to the mix.

full blast. my temps drop a whopping 1C LOL

im going to look into getting a new rad and ditching the chipset block as i hear they are massive flow killers.

also how should my loop go?
im running it now.
pump->rad->cpu->chipset->vga->res.

[BillA]

shit pH, please not those (I use them for testing @ max)
try a Delta AFB0812HH, 37.4cfm, 34dbA
if not enough go to a SHE

not well considered
"I presume you are moving outside air across the rad"

-> reverse your fans

[pHaestus]

Don't like the air cannons Bill? I also only use them for testing (but I have the sense to install oversized rads so that fans can be quieter)

[sandman]

might have fairly low flow, but honestly your temps don't seem that bad to me.

[litdie]

umm ok lol

im getting worse temps then i was getting with my air setup.

i didnt spend close to 300 for worse temps



also my side panel is off when i test. so whether or not which way the fans are going they are getting outside air.

and i was running 2 tornado fans. 84 cfm max spin and louder then hell. and only lost 1C.
-edit-

also i tried putting a 80mm fan near my cpu socket to see if my temps would drop... and they didnt. they actually went up.

[BillA]

seems you spent $300 for a learning experience,
also that you are a slow learner

[litdie]

dude did u read my last post?

i tried everything everyone suggested and nothing worked.

i was running 2x 80mm tornado fans. the fastest most cfm pushing 80mm fans on the market. didnt help.


i tried to put a 80mm fan near my cpu socket. didnt help.

i tried push/pull with 4 80mm fans. didnt help.

i have absolutely no idea what could be wrong.

You mentioned that you are sure that you have a good mount. How sure is sure? Have you re-mounted? Also 43c is not a bad full load temp are you sure about your old temps? I just pulled my wc stuff out of my existing setup to put into another case. My board is an ABIT NF7-S 2.0, CPU is a 2500+ @ 200 x 10, cooler is currently (sigh) an SLK700 with an unbearably loud 6000 rpm delta 60mm. Temps while primeing are low 50s c @ 22c ambient. The CPU will go faster on wc but thats as far as I will push is with these temps. Your setup while air cooling had same proccessor running faster (albiet with a better cooler running @ 1/2 speed)with temps 10c below what I'm getting. You will not get x'treme cooling with that rad sorry to say but I dunno if your temps are accurate and or if you mount is ok. A cool radiator suggests that no heat is getting into the loop. Also is your tubing 1/2 or 3/8 ID?

[litdie]

i was running a 947u and tornado 92mm fan at half speed.

i was barely breaking 40C full load at the same speeds.

at the same time of testing my water, my other computer running 200x11 with stock amd cooling was 42C load.

i decided to say fek it all. im striping it down and redoing it.
gonna reseat the cpu block, ditch the chipset, and change my cycle.

pump/cpu/vga/rad/res


ty all for all ur help.

[bobkoure]

I missed the part where you removed/remounted your block a few times and got pretty much exactly the same results. Did you do this? Apologies if you posted doing it and I missed it.
Also (and I'm out of my depth here as I don't use vinyl tubing) are your bends sharp enough that the tubing's putting a tilting load on the block? Might the block be tilted a bit because of this?
Nice that you posted pictures, but that fade-in/fade-out is erm... irritating...
Bob

[litdie]

yea i couldnt turn it off sorry.

but yea before i hooked it all up i made sure my block was making contact.

also my vga started to tilt off the core but i tightened it down and now it dont tilt.

the cpu block isnt tilting.

[Boli]

Strap those fans on to the back of the radiator and PULL the air through it, your radiator isn't too small but you are not going to see very good temps loading on the CPU/GPU and your chipset.

Just attempt to cool the GPU and CPU, and get a large passive heatsink for the northbridge - a case fan above that will help as well.

That should see you get some improvement on it all. and you should be able to cobble it togther with spares without spending any more cash.

[litdie]

im pulling air from inside my case thru my rad to outside my case.

but i have my sidepanel off so it doesnt really matter right now.

like i said, ive tried push pull and it doesnt help.

so at this point it is either the chipset block that is limiting me or my radiator.

im moving things around so i will find out soon.

[jlrii]

After looking around a little I think that with your current setup thats about the best you'll do. Your CPU block has a c/w of about .176 as reported by joe c, I could not find a c/w for your rad so for grins and giggles we'll use numbers from The Thermochill 80mm as tested by BillA as about .12 or so (with a Delta EHE). So neglecting the heat added to the loop from the gpu the total c/w is .296. Your slk-947u has a c/w of .29 in silent mode per CaseMod.com so we have a diference in c/w of .006 c/w (or about .6c for a 100w cpu) there. Now add in the added heat of the chipset block and the fact that the Micro will not perform as well as the Thermochill and you will find the 2c that went missing. Sorry to say high end air cooling can exceed the performance of low end water cooling. Those little c/w numbers add up fast when you multiply them by 100 or so watts.
