I don't know what model you have, but my old T61p with dedicated graphics had the same heating issues as my newer Macbook Pro.

My x220 has air vents at the back, on the left side and several at the bottom of its base. Even when it heats up the temperature stays very much controlled.

A T420 with no heat issues whatsoever. [edit] Not a great image but you can see where the vents are on the back and the left hand side on this image: https://t3.gstatic.com/images?q=tbn:ANd9GcSpIDoMt_OkYzjIF9E6HRSEJ0dMcaAVqUEgAurzsRjaF6kzLNKYGg https://t3.gstatic.com/images?q=tbn:ANd9GcSpIDoMt_OkYzjIF9E6... Doesn't matter how far I fold the screen back, the vents aren't blocked by it.

  From this review ( http://www.cnet.com/products/lenovo-thinkpad-t420/ http://www.cnet.com/products/lenovo-thinkpad-t420/ ): "Thick and bulky, with a keyboard studded with enough auxiliary buttons to look like a space shuttle control panel, the T420 is as old-school as a laptop can be." I mean, it's all a matter of trade-offs, as the parent says. Personally I have been using my Macbook mostly as a desktop replacement, so in hindsight I would probably trade the small form factor for better cooling and more sustained performance, for people using a laptop more "dynamically" (carrying it around daily), I can see mobility to come first. EDIT: Have you ever owned an ultrabook or a netbook ? I went from a T61p to a Macbook Air the the increase in mobility was significant. I used it on bed, on the couch, on the train, with no discomfort at all even after hours on end, unlike the bulkier laptops I owned before.

    I don't get this recent idea that a laptop needs to be as thin and light as an envelope to be "mobile". I have as much "mobility" with this Thinkpad as someone with a Macbook air. Next you'll be telling me I'm sacrificing mobility with my phone because it's twice as thick as an iPhone 6. This argument seems like it would only come from somebody who has sacrificed usability for thinness and needs to come up with a way to justify it. Does a Macbook have "increased mobility" over thicker laptops? I severely doubt it. The Thinkpad may have more buttons than a Macbook, but I've never seen this as a disadvantage... The Thinkpad keyboard is much nicer to use than the Macbook keyboard. I've owned both. I'll admit that the Macbook keyboard looks nicer though. But that's the point isn't it. Macs are for people who care what their computers look like more than how useful they are.

      >I don't get this recent idea that a laptop needs to be as thin and light as an envelope to be "mobile". Weight is hardly a big differentiator for MacBook Pros, as I understand it. The difference in weight between the ThinkPad T420, which the grandparent mentions, and the latest 15" MacBook Pro isn't that great: they weigh 4.9 lb (2.24 kg) and 4.5 pounds (2.06 kg) respectively according to the official specs. I suppose the ThinkPad will have a slightly heavier power adapter as well.

        Exactly, this idea that Apple have sacrificed things like useful ports and useful heat vents, for mobility, it's just flat out wrong. They have sacrificed those things yes, but not for mobility, for looking pretty.

      Taking your point to the next logical conclusion you would be okay taking a desktop computer with twin monitors instead of s MacBook Air. I mean be serious. Thinness and weight are critical to a non insignificant group of people. They could be people like myself who have to take his laptop to/fro work slongside gym wear and s number of books. I couldn't physically csrry s heavier laptop.

    I haven't had any of the ultra thin ultrabooks. I do have a netbook (slightly older Acer model), but the screen was too limiting on it. So now I use a Thinkpad X230. The differences between the X230 and my work laptop (HP Elitebook 8470) is night and day -- I have no problem carying the X230, but wouldn't dream of lugging around the 8470.

  How did you get your T420 to have no heating issues? What processor/GPU combo do you have? I have a T420 and have major heating issues with it playing games. I've tried everything: thinkpad fan control that turns the fan up to 7000RPM, clearing everything out with compressed air, replacing the thermal paste.. After a few years of observations, I think the problem may lie in software.. It seems like when I'm playing games and what not my CPU gets turboboosted, which stays there until it reaches about 90C, when it gets severely throttled, killing framerate and all. I use linux, so right now I have several scripts that goes and disables turbo boost. However, even at that point, it still will boost the CPU when running certain GL applications... Not sure why. In fact, I've noticed this issue on all Sandybridge laptops I own/have encountered: the 2011 MBP, a dell inspiron... Ivy bridge computers seems to have no issue with this (W530, 2012 MBP).

    > I have a T420 and have major heating issues with it playing games. In my experience, almost no consumer laptop is designed with a gaming thermal load in mind (aka heavy cpu + max gpu for extended periods of time). I'm not even sure it's possible in a conventional laptop case. ... I know this is completely useless advice, but don't do heavy gaming on a laptop without expecting problems. There are other form factors much better thermally suited. tl;dr: mobility/thermal-tolerance/performance, pick two

      One thing is that the T420 is not sold as a consumer laptop. Under Windows, running AutoCAD/SolidWorks will drive temperature of 90+ degrees. This laptop is suppose to be for those kind of work. Furthermore, I'm not even running heavy games. I'm running things like FTL, or older 3D games like RollerCoaster Tycoon 3, or even sometimes just watching YouTube videos at 1080p. Regardless, thermal performance under heavy load in laptop should either be tolerated, or the manufacturers should disable higher clock speeds. My W530 on the other hand has no issue with heat. Heavy gaming puts it to about 75-80C. It is also much bulkier in size. Edit: my dedicated graphics is off most of the time. Even then, CPU alone can drive the temperature up through the roof.

Perhaps your unit? I have a T61p still in regular use here and it's never had a heat issue?
- Kurtz79 12y ago
  Have you got dedicated graphics ? To me the issue was present mostly when gaming, not really during normal use (with the Macbook is the same). It failed me after a few years and sold it for spares.

    I believe it has an Nvidia card in it. While I did game on it awhile ago I haven't for several years now. Possibly I haven't pushed the hardware long enough to cause GPU thermal issues to arise.
