T61 Infact gets hot

[neednotebook]

No I am so sad. The notebook that boosted of some cooling features does get hot. Especially the places under the hdd and RAM. It is crazy that half the notebook is hot while half is cold. Wonder if there is some way to reduce the heat? Would it be because of the corsair ram that I added?

Anyone with T61 wanna confirm if theirs get hot as well. If not I might have to ask for an exchange.

Mine gets warm, never gets hot.

I wonder what is considered warm and what is considered hot. Sometimes I feel it is okay sometimes it looks hot.

Btw would you tell me what you use it for?? I run songs, do some word editing and run a virtual machine simultaneously and it gets hot/warm

EDIT: just used speed fan and it gives the following result

core 0: 35 c
core 1: 37 c

Core temp displays
Core 0 49 c
Core 1 50 c

Is this normal?

I did a search of old threads

and found this

http://forum.thinkpads.com/viewtopic.ph ... hlight=hot

so this looks fairly okay.

But when all these reviews call thinkpad cool do they just talk about the working surface or do they measure the temperatue at the back of the notebook as well??

T61/p is the coolest/quietest T series notebook ever amongst all thinkpads. Ofcourse it will get hot/warm every now and then depending on what you're demanding it to do but not all the time. The key feature of the cooling system is to minimize/regulate/limit the temperature when it reaches to a level of warmness or hotness, so your thinkpad is fine if it's doing it.

The intel graphics T61 here runs quite a bit cooler than the T42 with ATI 9600. However, the T42 fan is quieter than T61's fan, both at low speed.

[danny_isr]

the T61 is quite no doubt, but for me it just reminded me how quite my T43 was when it was new. now i understand that it needs a new fan.
i remember the Fan noise was about the same level of the hard drive.
it's not the case today...you get used to graduate changes.

[neednotebook]

okay this is what I discovered T61 is really cool and then get warms. But if I keep working or watching movies and hearing songs for around 4-5 hours it starts getting a bit hot especially under the RAM and hdd. I removed the corsair additional RAM and it looks like it generates more heat as well. So looks like there is no problem. Anyway I will keep an eye on the temp. for the next few days

thanks for the replies guys

Speed fan is wrong. Core Temp reads directly from the internal diode of the Core 2 Duo.

As CPU, GPU and fan assembly are on the left side (like T60), the left part of the laptop is hotter then the right side where there is any heating part (except if you use the optical unit).

It would be nice to use an heatpipe to drive a part of the heat within the right part of the frame.

MOD EDIT: Snipped for very very long quotes.

Sir, HDD is on the right side and memory under the palmrest on the machine under question and they do generate some heat depending on the type of brand being used. In addition, the fan, the gpu and the processor are on the upper left side and not under tha palmrest which you're already aware of. I am a natural left hander and I have never felt any heat issues on T6x machines especially on the left palmrest. I do admit T61 will get hot/warm on the right palmrest occasionally but to regulate and minimize this temperature, lenovo has put more heat vents on the bottom of this machine (T61/p) which works in conjunction with the new cooling system to make things cool, calm and steady.

I guess that answers why it gets warm after prolonged use of the computer

[danny_isr]

i have here T43 2Ghz and T61p 2.2Ghz side by side.

right palm rest warmer on the T43. left side warm a little on the T61p
totally cold on the T43 !


the T61 is the cooler machine. when i checked CPU temp . it was 36-39 for the T61p Vs around 60 on the T43. but honestly when touching the machine it doest feel like such a huge difference.

i have to add this : on the T61p i'm doing nothing to lower the temp.
on the T43 i am undervolting it when on IDLE. and power play is on minimum .

All the right part of the keyboard is much more cold then the left part. So they can drive some heat in this area. The whole keyboard can be used as a big thermal interchange. They use to do it for T61 where a part of the fan assembly drive the GPU heat to the keyboard base.

I noticed that too. THe right side is [censored] cool even after hours of torture. But the left sides gets warm and hot pretty quickly especially when wireless is on

It's always the same since T40... CPU and GPU, the hottest parts are under the left side of the keyboard. It's hard to handle more and more power within the same space.
