Replace Asus g51j heatsink

Hi there, i have a asus g51j 3d and i'm very pleased with it in every single way except its themperature. It reaches 219.2 ºF when i'm playing.

I've already modded its backplate but i want to give the next step and replace its heatsink for an aftermarket part that works better.

The problem is, i can't find anything about this procedure anywhere.


Can you help me??

 

There are not generally aftermaket heatsinks for laptops.

You can add some smaller heatsink blocks to it (see Forge's g51 cooling mod thread)

Unless you are using throttlestop the g51j runs hot but shouldn't power off from thermals.

p.s. post ur temps in celsius - its just accepted convention

 

Have you repasted and cleaned the vents recently?

It shouldn't eclipse 100C

I have a G60JX (same mobo) and the hottest its ever ran is 90C while running BF3 with High to Med settings. And ive never even repasted

 

these are my temps after running mass effect 2 for an hour. played in powergear battery saving mode, otherwise the temps would be even higher. I already have the backplate mod and i cleaned the vents today

Your temps look good. Unless you hit 105C on the gpu it is fine. Gaming in battery saving mode is probably too conservative unless your temps are giving you thermal shutdowns.

 

I play with battery saving but connected to the charger.
Anyway, i liked the all idea of the copper plates and I would like to try, but i'm worried about two things:
1- What measures of copper plates should i use as i intend to keep the backplate;
2- How can i mount the copper plates in a way that if it's needed i can send my baby to warranty

I haven't repasted because if i do that i will void warranty won't I?

 

can anyone help me?

 

What are your load temps in performance mode?

If you want to get ramsinks on the heatpipes for extra cooling, just look through the g51 cooling mod thread I linked earlier, there are plenty of examples.

94C is fine, I wouldn't worry unless you get to 105C

 

after playing mass effect2 with graphics on the heaviest set i got this temps

even if its temperature is fine i still would like to apply the ramsinks but what size? I have read thirty pages of the link u posted and i haven't seen an actual post where it stated the quantity and measures of those copper ramsinks. I want to make it

 

Groceries, Is there any evidence that having higher temperatures on GPU/CPU cores reduces the life of the unit?

I'm not talking like 105C+ where instant damage can occur. I mean like consistently in the mid 80's as opposed to consistently in the mid 70's.

I've always wondered. I figured you would know.

 

You aren't pushing your card in the least with those temps, still, you seem pretty insistent on this project. You must've just missed it, it's right there on the first page. Here ya go:

If you are going to do cooling mods, please read the thread carefully. At this point it is obvious you have skipped over crucial information.

As long as you're not running it within a couple degrees Celsius of its limit, the GPU itself will be fine. Those tolerances depend entirely on the manufacturing process and the electrical design of the GPU, so they're pretty solid. Nobody making video cards wants you to roast them (before the warranty is up*), so they either throttle or turn off when they get anywhere near those temps.

Running consistently higher temps, the only thing to be concerned about is the radiant heat getting to the VRAM and all of the components on the GPU card besides the GPU itself. Capacitors all have different temperature ratings, so it's going to vary highly between cards. If you're pushing a GPU really hard, and overclocking the pants off of it, that usually goes with overvolting or undervolting, and that can harm it physically. You really need people to be guinea pigs to know those tolerances (that's one of the good things about forum posts). People who blow up their video cards at least come back with useful data for everyone else.

* There is of course the nvidia chip-creep/underfill fiasco of the 8 series. That was a design flaw though, and it could be argued that entirely normal use alone after enough heat/cool cycles killed those cards. So it can't be taken as the rule.

Again OP has nothing to worry about, their temps are fine.

 

thanks for all your help
