Cannot cool Turion 64 x2 TL-60. WHY?

hi guys

i have aspire 5051awxmi and it comes with turion mk-36. i bought turion x2 tl-60 and changed the cpus (here the old thread http://forum.notebookreview.com/showthread.php?t=225751)

i can confirm that amd tk-36 on aspire 5051 cannot be replaced with tl-60 (tyler version). they have the same TDP - 31W, socket S1 and everything else but the sink cannot cool the tl-60. aftre replacing it the system run for about 10 min and then the vent went off. it countinued for about 5 min and then the system turned off. it looked like a cooling problem. i replaced the pads of the controller and the gpu (on this notebook they all have a common heatsink) and after an hour i turned the pc on. this time it lasted about 45 secs. and the vent was on its maximuum before the system turned itself off. so now i have the old mk-36, the old vent and arctic silver on the gpu and the controller.

what a waste for the tl-60. does anyone have an idea why it couldn't be cooled in this laptop? was it a failure or......... maybe faulty cpu?

why the heatsink cannot cool this cpu? it has the same tdp as the tk-36. where is the problem?

 

the heat sink is maybe to small or the fan is not blowing heavy enough

 

Too hot probably. AMD's are like radiators lol

 

here is a part of the docs for aspire 5050:

------------------------------
it clearly says that it can work with it. what about the fan? maybe another one?

 

did you do a bios flash

 

yes and i worked about 10 min as i said (lates 3315 from acer website). then the vent started rotating faster and faster and it shutted down in less than 15 secs.. buth before shutting donw i flashed back bios 3303, bacause 3315 has some problems with fedora. could this be the problem?

when i opened the case the put paste on the gpu and the controller i noticed the whole heatsink was really hot.

 

im looking to see how hot it runs. and what is the shut off temp also what gpu are you using

 

gpu: Ati radeon xpress 1100 - integrated on the motherboard. clock at 300Mhz, no overclocking.
the controller: ATI Technologies Inc RS480 Host Bridge (rev 10)
cpu (stock) turion 64 mk-36 (2 GHz, 512 kb L2) amd part nm: TMDMK36HAX4CM
cpu (new) turion x2 tl-60 (2GHz, 1mb L2) amd part nm: TMDTL60HAX5DC (it is the tyler version)

here more info for the cpus
http://en.wikipedia.org/wiki/List_of_AMD_Turion_microprocessors

i bought the tyler because it has the same tdp as the mk-36 - 31TDP. but its cooling head is almost 2 times bigger than the one of the mk36. but in both case it was under the heatsink. for the heatsink look in post 1 and follow the link.

Both cpus should be one and the same regarding the physical requirements. but somehow the tl60 gets a way hotter than the other.

About the temps:

I'm using linux as primary os and it shows temp the following numbers:
my cpu works at ~ 45C idle (no firefox just idle), with only firefox ~54C, under heavy load (linux kernel compile) ~ 72C. the vent goes on at about 49C and it is working almost all the time. i cannot messure the temp of the gpu because i'm using llinux. this is messured before opening the box for the first time.


now after putting back teh mk36 but with arctic silver on it and on the gpu and the controller the main temp is about 49 (with firefox and other apps), idle (nothing) about 42 and under load goes to about 58. but it is only about 4 working hours after applying the thermal paste and i cannot correctly messure the cpu-temp, because kde made something to the software.

 

you just stated that it uses 2 heatsinks and you only have one that will be a big factor of why the temp keeps on getting high so quickly. if you still want to use it set the power option to low and see what temps you get

 

no, you got me wrong. you know on every cpu in the middle there is a heatspreader. this heatspreader on the tl60 is twice the size of the heatspreader on mk36. anything else is the same. and in the whole system there is only one heatsink but it goes through the cpu, the gpu and the controller. it uses only one heatsink. but as i said the (i think it is called IDE) is just bigger, but it is still under the heatsink where it should be.

 

well you need change you heatsink and get a bigger one maybe from ebay

 

how can i see if the problem is with the cpu not the cooler? maybe the cpu is faulty. it shouldn't be getting that hot, since both have the same TDP 31W.

how can i check and see if the cpu is ok? (the bios recognizes it but it shuts donw almost imediately)old bios maybe because i'm back with the 3303?


Any suggestions other than new heatsink, because this is a notebook and there is no room for something else inside. maybe better (than arctic silver 5) paste or thermal pad or another fan (where to buy)?

 

you may have a bad cpu but 1st with your old cpu try these

it could be your psu it may be to small for it

 

maybe a power (voltage and wattage) problem..
I dought both of these cpu's have the same values.. (not sure)
maybe you need a higher rated power supply for the laptop??????????????

 

I called amd and they told me mk36 used higher voltage than tl-60. so the higher voltage can make the tl-60 hotter, they said. but i think the controller can automatically adjust the power supply to the cpu. then i was advised to call acer ask them

i called acer (as now i'm with the old cpu) and they said "no warranty" because the notebook has been opened (I knew it.) after some conversation they offered me to send them the notebook and the cpu and they'll change it for me. now I'm waiting to if it is going to be free and what'll happen with the warranty.

Personally i don't see any logic in this. either me or the technition will put the same cpu in the same notebook with the same cooler. Where is the point in who is doing this? if it is not working in my case, why should it work when they do it?

I'll wait for the answer from acer.

 

honestly... sounds like BS to me..I agree with you..are they going to install it with "magic make it work gloves on" NO..
Do you have the latest BIOS installed???
check the ACER EUROPE support site.. The U.S. site is worthless.....
I don't think Acer will do ANYTHING for FREE?????? LOL
they won't even pick up the phone...

 

new update guys:

I have 2 of these notebooks and i saw something very interesting.

first of all the specs:
Notebook 1:
Turion 64 mk36 (2GHz 512Kb L1)

Notebook 2:
Turion x2 tl-60 (2GHz 2x512 KB L1)

Both cpus have TDP=31W (from AMD website). Both laptops have the same motherboard, the same video (ati xpress 1100) and the same northbridge controllers.

take a look at the pic now.

GPU, CPU, NB and the sensors use one and the same heatsink. when i changed the cpu of one of the notebooks i replaced the ThermalCompound under the GPU, CPU and NB with Arctc silver 5. The original ThermalCompound was some kind of rubber, not metal, maybe some kind of soft plastic, or even a soft tyre.

Only the sensors kept their orig. compound because there is a 1mm distance between the heatsink and them and couldn't fill this with artic silver.

For measuring the temps i used Core Temp 0.97.1 and speedfan 4.33. both apps report the same numbers. the mk-36 works constantly at above 56C. the tl-60 (with AS5) works at about 54C, under load at about 59C.

The problem is:

The notebook with tl-60 gets REALLY HOT in the place where the North Bridge Controller is. Although the mk36 works hotter, the overall temp on this notebook is lower than the temp of the tl-60. and this happen only in the place of the NB.

The nb chip is about 20x20 mm. i lapped the heatsink above it and used AS5.

Do you think i should put back the original Thermal Compound in order to cool down the nb chip. it is really not comfortable to work on the tl-60 because in 20 mins it is really hot on the keyboard? What could be the problem? Too much of AS5? I tried with lower amount - the same result.

I cannot measure the temp directly on the nb but with the orig compound it is cooler.

Any ideas or advises why this happens?

 

i just buy Acer 4520 with AMD Athlon ... its pretty hot compared to my Toshiba Intel notebook

 

that's because amd athlon is there desktop cpu's there are not optimize for notebooks. return it
