Temperature vs Peformance

I purchased a P150HM based laptop from pcspecialist.co.uk a UK based reseller, it's my first laptop with any real power as before i owned numerous Sonys, Dells, HPs etc.
It has an i7 2820 and GTX 485m, and i have been playing many games on full settings for the first time and i am blown away by how good it looks.
I run the GPU either stock or OC'd to 625/160/1250 depending on the game as the OC does provide a slight improvement on some, and i am using the 275.33 drivers.
The GPU temperatures i was getting whilst playing were starting to worry me, as on full load they were reaching 90C+ and occasionally this crashed the system. So i purchased a decent latop cooler and now the temperatures run on average about 10C lower.
My question is this, Should this improve the performance of the GPU? And will it increase it's lifespan? Are there any other improvements that will result from running at lower temperatures?

Cheers.

 

I am in a similar boat having ordered a p150hm with i7 2720 and gtx 485m which was shipped today. It would be great if you could tell me which notebook cooler you are using as I just got one myself for when it comes. I also have never owned a powerful machine before this and have know idea about how to OC or when to OC; I guess i should look into it.

Anyway, I too would like answers to ascable's questions.

 

I have a Cooler Master Notepal U2, it comes with two usb powered fans which unlike many other coolers you can position wherever you need to, using it without the fans attached you still get much better cooling, it's not the best looking cooler out there but it works amazing

Cooler Master Notepal U2 - Notebook stand with notebook fan - 17" - black: Amazon.co.uk: Computers & Accessories

As for OC'ing, there are plenty of useful threads on here to help you out, i can recommend using MSI Afterburner as it is an easy to use program, and comes with an on screen display function which allows you to monitor temps, framerate, GPU usage etc, whilst playing.

I would say yes because the improved cooling will mean that the computer in general won’t have to work as hard because the inbuilt fans won’t have to run as hard or fast because the cooler will be doing some of it. And of course it should improve its lifespan if you think about it your computer has less work to do and you should have a performance increase too because better cooling means better temperatures so your GPU works more efficiently.

 

Thanks.

Can I also ask a few more things: do you need to overclock and how big are there risks of overclocking? I want my lappy to last me at least three years and my main concern is that overclocking will reduce its life expectancy.

One other thing about the cooler, where do you position you're fans for you're p150hm, and is it a bad thing that my cooler does not have positional fans? I am using the Zalman 2000 that was the highest recommended cooler in these forums; would the U2 serve my p150hm better and where would you adjust the fans for optimal cooling?

 

I also own a U2, and can recommend it. On my w860cu I place the fans over the vents near the ram and gpu (the center of the notebook). I find that this lowers temperatures more efficiantly than placing them directly beneath the fan intakes (which a lot of people on this site recommend for some reason I do not understand).

What's great about the U2, is that you can remove the fans, turn it upside down and use it on your lap aswell

 

with the oc its lifespan decrese from 10 to 5 years......i guess
but after 2~3years you may already purchase new platform.......bcz when that time a mid class gt855m/gt955m will blast gtx485m
exp:gt540m>=8800m gtx,gtx460m>= 8800m gtx sli

 

After experimenting with the fan position on the U2, i find placing one underneath the GPU fan and the other beneath the GPU itself works well. I don't know if it's the best cooler available for the p150HM, i looked at the Zalman ones as they are highly rated, to be honest the main reason i bought it was because it was cheaper.

 

Never reach 90°c myself when doing heavy gaming.
Im using the max "safe" OC in AMD Overdrive.

 

Do you actually need to overclock a 485m to be able to max out high end games? Can't I do this by just keeping my computer uncluttered and using game booster?

 

a China player oc quadro4000m

core from 475 to 750
vram from 1200 to 1400
shader from 950 to 1500

this card is very dangerous , a shorter life ?

but 336 cuda cores beat 485m's 384

you can see the result :

P3699

3d06 20958

because the new tech is better , 485m is out , 470 is out too .

so the 470m could OC a safe value , but 485 is too hot , so please OC a suitable value , summer is terrible .

click hear to see the trueth

and see what's the really powerful cooler method of barebone laptop

you need to disassemble the machine , or use water-cool , or drill a hole on the D board and use fans to blow the air to the surface .

a notebook , is a tight space full of parts , must use powerful and direct method , not a thermal pad or thermal compound .

and then you never occasionally crash out , no blue screen , because you control the temps and control the OC value!

 

I have heard of the rule that you may double the life of the GPU if you drop your GPU temperatures by 10C.

 

That's because it's not true. GPU's are rated to run up to a certain temp, usually around 95C, max. As long as temps stay below that, 10C either way won't make a big difference on the life of the card. Generally speaking, even the powerful 485m stays around 70C under load for most. Going to say 60C isn't going to make any difference in the lifespan of the GPU (it's rated for much higher, and running it within normal operating parameters won't adversely affect it)

 

I have thought that max temperatures, such as 95C, are rated for transient situations not for long sessions of usage. I would be mostly interested in the way the idle temperatures may affect the lifetime of the gpu.
