cooling my laptop

[Canine Owner]

hi, I own Lenovo y50-70 8gb and 4gb gtx860m
recently i used to play farcry3 and BF3 and other games but after playing a heavy game like watch dog on ultra settings which was awesome i noticed that the CPU and GPU tempratures were higher than those temp.s while playing fc3 as i mentioned watch dogs is heavier and contains more graphic details, whatever while playing FC3 the temps were max. C
CPU:59-60 GPU:57-58
while playing waatch dogs the temps were max. C
CPU:64-65 GPU:60-61
which are more concerning for me so I decided to reduce this heat by buying a cool pad but I noticed that the laptop has a small opening to get air from so I think its better to get a small fan 80mm with high air pressure and air flow and high rpm like coolermaster blademaster
http://
here is a video which shows the cooling strategy of lenovo y50,
[video="https://www.youtube.com/watch?v=LCcWDOjhrUg&list=FLQQ3x0Cy96PGhyUKCfX3J_g&index=1"][/video]
offcourse i am going to put the blade master beneath the two small laptop fans so it pushes high pressure air that get through the fans and helps cool the aluminum part that absorbs heat from the heat sinks as showed in the video.
Also i am thinking about geting aluminum mesh and out the laptop on it and the fan will be attached to this aluminum mesh
nut i think that this aluminum esh will not absorb heat from the laptop because its bottom is made of plastic which is not a good heat conductor , Am i wrong?
any suggestions??
sorry for long post

To start with, how do you plan to power this 80mm fan? The circuits on the board and power jack system aren't designed for the amperage likely to be drawn through a fan that size, especially in addition to the load on the system from the GPU and other components that are already tapping the source.

Are you planning to power this externally? Any way you look at it, it's probably a poor idea, but I'm all for modification of anything that can be safely and effectively improved, so if you are successful, let us know with video or images, and report back on it.

As far as any mesh is concerned, if it has air passing through it in any amount significant enough to improve the unit's cooling, it's unlikely to get seriously hot enough to cause any issues due to being plastic.

Your temp are fine ! I play at 70C CPU and 80C GPU GT 520MX.

What are the temp now ?

Use a cooling pad

these temps are more than ok, leave it or you could destroy it.

surely, i am going to power this fan from external source,why do you think my idea is poor?i just want to make effective cooling to reduce those loading temps instead of buying expensive cooling pads which will not give me more cooling ability than the 80mm fan . also, I saw cooler master pads U series which use aluminum surface to absorb heat from laptops although the majority of laptops' bodies are made of plastic not metal, that's the questionthe same question is does metal mesh in cooling pads absorb heat??
thanks

As mentioned, your temps are WAY below TJmax, the threshold where the system starts throttling things. You don't have ANY need for additional cooling right now, unless those are idle temps. If those are loaded temps, you're fine.

whatever i need cooling solution now or not , is this idea going to work?

I wouldn't worry about the material, as it seems you're just trying to make a better cooling pad and not actually stuff another fan inside the laptop, since the airflow is the only part of the idea that's likely to offer ANY benefit, however small. I don't think the material is going to matter much as a consideration nor be very effective as a heatsink per se, as the plastic case of the laptop is unlikely to transfer any meaningful thermal exchange to it anyhow. I'd probably, if I'm now reading your intentions correctly, just find a really cheap laptop cooling pad and modify it to accept the fan you intend to use and connect the fan to it's current power cable in place of the existing fan if the unit has an AC to DC adapter and is compatible with the power requirements of the fan you intend to use.

I don't think it's going to make a lot of difference though, as I've tested similar strategies using a 14" room fan blowing directly onto and into the intake of the laptop fan with the laptop sitting on the room fan's grillwork, and also in reverse, with the room fan blowing away from the laptop, and only registered about a 1-3°C CPU and GPU temp difference so it's pretty unlikely to have an impact on those core temps.

yes, now you really read my intension,but now i noticed an increase in the maximum temperatures I mentioned before wunder the same load and also i didn't change the laptop's place or settings but both temps of CPU and GPU increased 2degrees C and thats real concerning for me as the cooling system weakens as I suppose , I bought this laptop from nearly 3 months .
any thoughts?

Your i-series CPU doesn't even begin throttling (TJmax) until 100°C and wouldn't trip it's thermal protection shut down until about 115 to 120°C and the GPU should be fine up to 85°C. Anything within a couple of degrees of those temps is when you should be concerned. You're WAY below that. I wouldn't be worried at ALL! If your CPU temps go over 90°C and your GPU goes over 80°C, THEN start to be concerned.
