Thanks again for ur efforts as its help to clear the doubts on its temp.
No need to worry so much with this stress temp. as it will never happens in ur normal usage.
Nice temp. for CPU max at 83c, GPU 74c under FULL stress test showing the FULL copper heat sink is working great . HDD temp can be taken care by using suitable cooler pointing to the air vent or swap with DVD, no worry.

Its making me to change my focus to Y480 & oc it to GTX660M.

It seems that it can easily oc to GTX660M with only slight change in temp.

TurboBoost is auto on during stress, refer test results b4 & after stress at post #135.

GPU go back to default base clock tho' u OC it.
can u post GPUz for gpu info.

GPUz info after OC?

Try whether can oc GPU/memory to its limit 100% without throttles. Do monitor ur temp.

If any throttles, it should reflect during Furmark. But ur gpu not throttles.
Just curious why gpu base clock return to default 835mhz instead of oc 930mhz when u stop Furmark.

Refer to gpuz & msi burner info below. u post this after stop Furmark?

Furmark Test Result

Its different from ur OC setting below.
OC GTX 660M Boost 950MHz to 1045MHz ! Memory from 1250MHz to 1312MHz Dual Channel is 2625MHz!

If same setting, gpu OC base clock is 930mhz with boost clock 1045mhz.
Wen Furmark finish, gpu should clock 930mhz & not 835mhz(default).

Thanks. Glad to know u OC without any throttles.
Wen free, try to max OC & check any throttles during Furmark.
Wish u can challenge GT650M oc to GTX660M
Good night...
Thanks for clarification as I also thinking the same.

GTX660m= OCed GT650m. If GTX660m dont move, better watch up Y480 lol...
Its nice to squit out all the remaining juice & dont waste money.
If ur average fps is 25. Extra 5-6 fps will really help.

Its not recommended to OC GPU in the long run, as the extra heat will shorten its lifespan.
u ve to be pro in using necessary tools to monitor the temperature & stability with a suitable cooler, otherwise u may burn ur hardware.
Any way, do it at ur own risk.

There is a guide for Y580 in chinese site HERE.
Take note DVD location was not specially designed for HDD, as it don't ve proper HDD ventilation & shock protection. Watch out the warranty sticker as u may void the warranty if broken. Alternatively, choose a suitable cooler with fan pointing to ventilation hole is a more simple solution.

Killer model sure sell like hot cake . May be Lenovo holding some stocks for coming PC fair so watch out & be fast.
iirmc DDR1600 + DDR1333 = DDR1333 performance, its better to get the same speed ram for faster performance.

New generation of DV6 still no sign in the market. Guess we ve to wait till they clear their current inventories during pc fair.

What is the best cooler for Y580/ Y480?

Let's look at Y580 and its heat distribution,


Notepal U3 is one of the best solution as we can adjust the fans pointing to the air vent at the bottom for effective cooling.

U3 is more effective in cooling as its increase the airflow inside the laptop. Just get some air filters place on top of fan to reduce dust.

There is one here, interested.

Do u feel warm/hot around left palm rest/ touchpad of Y580/Y480 during long hour gaming or stress test at room temperature?

Is the fan auto boost faster from idle to gaming/stress test?
Wonder any way to increase the fan speed when idle to improve the cooling?

can we adjust/turn off the BIOS automatic fan control?

can u post screen for system summary & sensor status from HWinfo64 HERE.
Guess HWinfo could adjust the fan speed according to temp.

For Lenovo Y570, there is a button for themal management to control the fans speed HERE
Is it available for Y480/Y580?

Y570 Thermal Management button
