European owners - does 240 V make lappies run hotter?

I am visiting a country that uses 240 V and my V4000 is running much hotter than it does in the States. I bought an AC adapter from the local HP distributors because I forgot mine at home, so I know it's the correct part.

Could there be another reason why it's running so much hotter than it does in the U.S.? I will be here for a few weeks, and I don't think it will cause any damage, but it does concern me because in the States, using the same setup (I use a laptop cooler which I brought along with me), it is always absolutely cool to the touch.

 

Do you know what your CPU and HDD temps are?

 

Actually, the european standard 220-240 V is cleaner and should make your lappie run smoother, in theory.
Check the BIOS or download some program that measures the CPU temp.
Also, you should contact HP, they are quick to reply.

Just wondering, is the AC running unusually hot?

 

If the AC adapter you bought outputs the same voltage as your original US ac-adapter, then it shouldn't make it any hotter.

However, ambient temperature definitely affects the cpu/laptop temps. What is the temp there?
How about humidity? (though i'm not sure if it has any effect)

 

Yes, I agree with fill2k. If the new adapter you bought is of correct rating( AMPS and voltage on DC side) it should not be any different than US adapter.( Infact all most all laptop adapters are 110-240v auto).

Ofcourse, ambient temps make lot difference( even 5C more ambient make it as much as 10C more hotter).

BTW, typical power supplies( computer Power supplies) are little more efficient with 240v rather than 110v. If you take some of quality power supplies which are rated for 110v and 240v( most of those are) the efficiency rating is more for 240v input. And heat also in general less because it needs carry less current at higher voltage.

 

Thank you all for the help. I will try the suggestions of measuring CPU temp and contact HP if necessary.

fill2k, I am in a subtropical climate. Obviously it gets very hot in summer, but right now it is winter so ambient temps are quite mild, comparable to springtime in New York. But that is a very interesting point. I remember that when I lived here some years ago, I had to buy a fridge specially made to handle this climate.

The AC adapter has the right markings and of course it is an HP product, so I don't think that is the problem. Also, since I posted, the laptop seems to run more "normally" most of the time, heat-wise, so perhaps it is related to a certain app or something. I'm not overly-worried, I know these machines are meant to operate normally even without laptop coolers, but I guess I was so used to having it cool to the touch that the unusually hot surface surprised me.

Thanks for the help.

 

If y ou live in Seattle in the US, and go to Sicily or Malta in Europe, your lappy will run hotter ... because of the environment (girls are hotter, you know )

Otherwise, most AC adaptors work on 100-240V input and produce almost identical output.

 

hehe, I live in Chennai, India, and my notebook runs crazy hot

sometimes upto 60C even with nne of the vents covered

 

If your new AC adaptor output really a correct voltage, then it should not be hotter. The AC itself may slightly hotter since it converts higher voltage to regulated DC.
