    HDX 16t Heating issues

    I bought an HDX 16t back in may, and have loved it.
    But I notice, after installing Speedfan, that this thing gets VERY hot

    even propped up a half inch off the desk, playing any game that's demanding gets the thing to a blistering 96*C... WAY too hot for a laptop.

    Now here's the interesting thing, when it hits 96* it stays at 96*, like the fan kicks into turbo mode or something.

    So my question. is this a defective product? or do all 16t's have this issue?

    and if it is an issue I can fix, what are some ideas? besides getting a cooling pad, I don't really like the extra bulk under the front of the laptop. But for fixing the comp, should I mess around with some setting somewhere to make it kick into turbo mode at a lower temp? (like 88), should I under volt it? it's a new laptop with no trapped dust.

    thanks for the help :)

    undervolt CPU.. My T9400 ran at 1.175 V and when i dropped to 1.125V , temps dropped by 20C... Get a notebook cooling pad... also use compressed air to blow dust out of you fans... should have no problems then... and use CPUID Hardware Monitor to monitor temps...

    Undervolting is all nice and dandy, but when you get a new laptop and it runs hot and your only option is to undervolt (run the system out of specs) to prevent the lappy from burning to the ground...it's bad.

    So if you HDX 16T (Intel) overheats, it means that my DV6 Turion Ultra 2.2Ghz (running hot also) is NOT the problem. I always blamed it on the AMD CPU, as they are supposedly running warmer than Intels
    The issue is with the improper sizing/design of the cooling system of those HP lappies. Undervolting is an awesome solution to drop temperatures and save on batteries, but seriously we are doing it mostly because some laptop's thermal design sucks.
    They will have to consider using one heatsink/fan combo for the CPU, and another one for the GFX chip.

    My HDX CPU goes to 70C and I thought that was HOT :O (Well its still hot enough to make the laptop throttle the cpu speed)

    what the heck??
    my hdx also goes to 70c and i thinik its hot
    96C...wow
    whats the maximum temp that thing can take??

    anyway...does undervolting affect the performance or have any 'side effects'?
    and increasing fan speed also...does that have side effects?

    Undervolting as NO incidence on performance.

    But you want to check for stability with appropriate software (prime95, orthos), to see if CPU (at lower volts) still runs 100% error free.

    As for increasig fan speed, there is no way to do it with hP laptops I think.
    You can set to fan to "always on" in the BIOS, that doesn't turn it into a turbine, just to start exhaust heat earlier.

    but then whay all the yap about coolers when you can just do that??

    and are those software for checking errors(prime95, orthos)?

    mine used to got to 90-100C when playing brothers in arms hell's highway and i ahd no problems liek throttling... now it goes only to 80C at most but quite rarely...

    Yes. Well, it's twofold. It will load the CPU to the max, looping calculations to no end. So the temperature builds up and then you see how hot it runs at 100% (worst case scenario). At the same time, if there is a miscalculation (ERROR) the software will tell you, which would mean that the CPU is not stable.

    It's a way to test-proof undervolting. Stability, and running cooler compared to stock settings...that's why you'd run either Prim95 or orthos for a decent amount of time. Minimum 1 hour for undervolting a lappy I'd say, and up to 8 hours when overclocking a DESKTOP gaming rig

    What are the side-effects of "undervolting" ?

    And can it be undone through a format?

    Less heat produced, more power saved (P=IV)
    Yes it is undone by a format.

    I was talking about the negative side-effects? There are none?

    I mean, if the CPU doesnt get all the power it requires at a certain point.. wont it fail, shut off, or something else?

    And is it also correct undervolting wont work on a quad CPU? Thank you.

    You can undervolt anything including quads. There are no side-effects if you test for stability (i recommend IntelBurnTest, it tells in 15 mins what Prime or Orthos take 8 hours to do).

    While tweaking your voltage till you get stable there is a risk of crashes and BSODs, but that's all.
