this k46cb can play dota2? and i need open many tasks when i study >.<
im going to buy this but scare easy overheat.

In all honesty, I have stopped recommending the K46CB already, since Haswell models are beginning to show up. Look for Acer V5-473PG which vents air to the back that meant better cooling compared to the side venting of the K46CB.

Plus the V5's memory upgrade is much easier than the K46CB.

Tried it with Tomb Raider - Performance was good on the default screen resolution (1366x768).

I though Acer always have overheat problem. All my friends that used Acer before complained about it.

Every laptop, from Acer to Apple if you want to think about it, has heat problems, namely on how best to actually remove said heat. There is nothing to say that Asus is hotter than Acer or Lenovo is hotter than Apple.

I bet that if your friends all use Asus they would point out that it also have heat problems.

In the case of K46CB vs the Acer V5-473PG the difference happens to be how the hot air is vented out. The K46CB vents out the heat from both CPU and GPU to the left side of the laptop running under the keyboard, and with your arm placement you would actually feel the heat. It is the same with the Y400/Y410P from Lenovo, again venting out hot air to the left of the notebook.

The V5 vents out hot air via the back. Hence the better cooling feeling as one would say.

I understand that all laptop got heat issue. But, Acer seems to get overheat that causes force shut down easily. At least, all the Acer users that I known have such problem.

Strange. Mind passing me the models and the specs of the Acer that has such a problem? Because I haven't encountered such problems, since, well, a long time. Most modern CPU's now have thermal throttles, dating back to I think 2005. Too hot, and the CPU throttles down to keep temps down.

They use to make programs to stop throttling behaviours.

great laptop, just bought it yesterday. very capable of doing some light-medium gaming at good fps (30-60). thats at native res. Got it for RM 2150, and for the specs it gives its quite a bargain. other laptop is more expensive and have lower end gpu like the 720m.

I don't know which model but it was few years ago. Maybe Acer have improve their cooling capability like the one you recommended.

hi,
the V5 i5 1.6Gb is better than k46cb i5 1.8Gb?
im getting either one so would like to know more reviews bout these two models

besides, does 4Gb ram sufficient for w8? or it's better to upgrade to 8Gb when buying?
how bout the warranty? i know asus provides 2years international warranty but i dont know about acer, 1 or 2 years? is it possible to extend the warranty to 3years like dell?

thx

Yes, Acer;s laptop can upgrade warranty

Different generations, the Acer has Haswell while the K46CB has Ivy Bridge. Cinebench puts the Acer 4200U faster than even a 3517U (Operating at 1.9Ghz!)

4GB should be enough, if you want there is an extra slot free for you to upgrade the RAM. My suggestion is to test out 4GB RAM first, then see if you do need the extra power. My use, seems to not really need the extra 4GB for gaming, but if you do other work then maybe you do.

Yes, Acer starts off with 1 year but you can extend when you purchase.

alright, thanks hehe

Can just topup their ram rather than replacing it?

Most laptops would have at least 2 slots, and you can just add a 2nd ram in there to top up, unless it comes shipped with two modules using up all slots already..

Hye. anyone try using Ansys Fluent on this thing? Is it ok?

Dear SiFu, how this K46CB compare with the current Lenovo Z400T (5936-6604) i5 - 3230M?
I heard one salesman told me that the Z400T got 2 fans build in or did I listen wrong info?

The i5-3230 is a full bore 35W processor compared to the 17W this one sports, however you look at it, the Z400T is going to run faster, and it is going to run hotter than the K46CB so whether it has two or one fan does not in either way a good comparison, since other things such as thermals and design will come into play.

It is more of a "salesman" talk if the reason he pushes the Z400T is because it has two fans. Heck, I'd say it has two, carrying a 35W processor.

Then again, I do stress that the K46CB will be a pain if you intend to upgrade ram since only one slot is easily accessible.

Oh, I see... Is there any news or rumor that the Lenovo Z400T would be a refresh version of Haswell Processors?
I was doing survey for myself and my friend as well, but myself planned to buy a new lappy by the end of this year or at new year (funding up some cash at the moments ).

So I know pc/laptop techs are moving fast, so currently is eye-ing on the K46CB comparing to the Z400T. So not so sure Haswell version models for both of those will reach our bay by end of this year.

Safe to say that K46CB, Z400T will get the Haswell refresh, and my advice is if you can wait, do wait. So far Haswell's launch is being staggered into the marker, with few models from several manufacturers.
