First Water Cooling build (Fx-8150 <-Proc from Hell??)

[Tomazy2]

Hy guys, need help, I'm all ears

-> Proc is running on STOCK SPEED (3,6Ghz) without any OC !!
-> And my room temp is 28C

I got Amd Fx 8150 proc and on stock cooler i had like 60-65C (on Asus Suit II ), 35-40C (on Temp Core) while plying BF3. While runing PRIME Temps started to go off the chart 65C++ (after 5min) So i decided to go with water cooling.....
Btw i don't get it how can the two aplication's show different Temp on the same sensor?? Can someone explain ?? Whitch one is correct ?? It's kinda rly annoying...


Few day's ago i did my first build WC from EK:
(i know that the rad is overkil just for only Proc cooling, but i bought it for later option's of upgrade)

EK-Supreme LTX AMD - Acetal
EK-Reservoir Combo DCP 2.2
EK-DCP 2.2 (12V DC Pump)
EK-Multioption Tube 100mm
EK-CoolStream RAD XTX (240) Dimensions (LxWxH): 280x130x64mm
EK-PSC Fitting 10mm - G1/4 E-Nickel
TUBE Masterkleer 13/10mm UV - BLUE
Arctic Cooling MX-3 thermal compound (4g)
EK-Cable Splitter 4-Fan PWM Extended
EK-PSC Adapter 45° G1/4 Nickel
Xigmatek XLF-F1256 Blue - 120mm
EK-Ekoolant CLEAR (premix 1000mL)
EK-Backplate

Few pic's:

-Thermal paste I applyed on the middle of proc than let the pressure do the rest
-Loop goes Res->Pump->RAD->Block (i went that way cuz of sorting,
acctualy tutorial said it doesnt matter just that RES->PUMP are together )
-On rad i mounted Push Pull configuration (4fans CFM 61 , runing on 1100rpm), air blowing Out-In
-All the bubbles are out of the loop ! Non of that freaking bubling
Now i'm getting 54C (on ASUS Suit II) and 35C (on Core Temp) running PRIME for like 30min on proc STOCK speed...
Idle temps are 37C (on Asus Suit II) and 14C (on Core temp) ??? wtf Room temp is 28C ??

But i think temp's are still to high for WC ???? Is it normaI ? Did i do anything wrong

I had all AMD proc's before this one but none of them didn't heat up like this one, like it's from HELL


Sry for my bad english

When running prime on full 8 cores Asus suit show's 54C, but the water temp in loop is around 39C (i put the thermometer in the reservoir)??? Shouldn't the temp of the proc be the same ???

No your processor temp will always be higher than the coolant temp to some degree. The reason we stress so much extra radiator is to keep the water temp lower. Beyond that theres alot you can do with tuning the system in to help temps. Most of the time people push way more vCore than the FX chips need. I run mine around 1.23v @ 4.0ghz, your results will probably vary but thats the biggest key to keeping them cool.

hm... but mine on stock speed has 54C ??? Is this normal or should I have lower temps ??? Between water and proc temp there is 15C difference ???

Is asus sensor on the motherboard accurate ? The core temp show's different
Which temp should i trust ???

 

[Conumdrum]

Umm WHAT program are you using for temps? You have AMD. ONLY ONLY use Coretemp, the latest one and pay attention to ONLY ONLY core temps.

Try that.

Lastly, without proper informed bleeding of a top rad you probably still have massive air pockets in the rad.

And, that is NOT overkill rad for that chip.

AND EK liquid, a waste of money. And possible clogged loop later.

OK TempCore it is... About the Rad, is it possible that air is still inside, cuz i don't hear that blobing sound anymore like i did when i filled the loop ??
Which liquid is better and what's the difference

 

[Conumdrum]

Distilled water $1.15 a GALLON in Las Vegas. Pure, no additives and you buy a $7 Killcoil that will last for years. Water is the best coolant, and any stuff that has 'marketer writing please make my boat payment crap is just that, crap.' You also have to drain and refill every 6 months. We preach it here, welcome to a forum that knows about watercooling.

And way yess on the bubbles, we see it ALL the time on top mounted rads with barbs facing down.

Probably every two weeks someone has the issue.

 

[m0r7if3r]

The bubbling sound is the air bubbles, once it bleeds it won't sound like that anymore, it will be silent (uncompressible fluid and what have you). If there's any noise it will be sloshing and it should come from your res. A good way to tell if you have a bubble stuck in your loop is to turn your pump off and watch the water level in the res. If it rises when your pump is off, you have a bubble.

 

[Tomazy2]

Well when i turn the pump off, water level in Res rises for like 1-1,5 cm... Gona try to get rid of them, then gona PRIME again and report back

Temp dropped.... result

---> Core Temp
Temps in Idle : 10C
Temps PRIME : 34C

---> Asus Suit II
Temps in Idle : 32C
Temps PRIME : 54C

PRIME was running for 15min... Fan's on 1100Rpm... Room temp is 26C

Are the temp's normal ?

What's the best OC for this proc ??? I have Asus M5A99X EVO


Btw i'm still wondering why different temp readings ???

 

[m0r7if3r]

You're probably better off asking this in the AMD forums at this point. I don't know enough about those chips to answer your questions about the temp sensor differences and such, nor how to overclock those chips, and I'm not really sure anyone else here does. At the very least the % of people who do will be much higher over there.

 

[Tomazy2]

I have question, which non answered. Temp of proc is 54C, but when i checked water temp in loop it was about 40C ? Is this maybe cuz thermal paste is applied wrong so it does not conduct enough heat from CPU to Block ???

Coretemp seems to have a bad reading from the BD's sometimes, asus suite takes its reading from a sensor under the processor, coretemp takes its reading from a diode in the processor itself I believe, I would definitely say you should check out the AMD forums for more on that, I forgot what the offset temp you would need to use in coretemp is for a more accurate reading.

AMD boards tend to use more voltage than needed for stock operation, so you can lower them and still get rock solid performance and lower temps at the same time. as for a good overclock, that varies from processor to processor so you would have to play around with it, if you start hitting 60c in coretemp under load with an amd its normally time to stop the OC there.

I have question, which non answered. Temp of proc is 54C, but when i checked water temp in loop it was about 40C ? Is this maybe cuz thermal paste is applied wrong so it does not conduct enough heat from CPU to Block ???

This is the same as if you were using a fan, your room temp is 26c, but your processor is running at 50c, the water will be cooler than the cpu just like your room temp will be cooler than your cpu. hope that helped because I can't seem to come up with a better explanation. Rememer your cpu is hot, the water is dissipating the heat and then the rad is taking the heat out of that as well, the heat it dissipates has to come from somewhere (the cpu).
so cooler water temps are normal than cpu temps.

If you think that rad is overkill, you should read the stickies on calculating heatload and how much rad you need, you do seem a bit uninformed on those things.

Between the core and the water, there is quite a bit, thermodynamically, that has to happen. The heat has to make it to the top of the dye, through the TIM inside the CPU to the IHS, and then go through more TIM to make it to the block, where it interfaces with the water. For all the heat of the processor to transfer across that (and not merely be contributed to warming something), the core must be at a certain temperature.

tnx for INFO man ... now im running the same

water temp in loop 38C... this is fishy and I'm gonna re-apply thermal paste

Not really, Your water temp is appropriate for the rad you have with the fan speed you are using 1000rpm.

i got XTX 240 ?!

 

[spitter3]

i got XTX 240 ?!

So divide the watts the rad can dissipate by 1/3, 1000rpm 100 watts dissipation @10c.

The Fx-8150 is rated at 125watts so water should be about 12.5c above ambient at full load.

 

[m0r7if3r]

So divide the watts the rad can dissipate by 1/3

Dividing by 1/3 = multiply by three. You can either divide by 3 then multiply by 2 or just multiply by 2/3.

Should have said take off 1/3, LOL
