How much Difference a High Quality FAN makes??

Gang
I've been wondering this for awhile. I have a thinkpad x120e and several lesser notebooks [asus, sammy]
The compatible part num in this case, I think [not positive] is KDB04505HA
I assume that there are fans, then there are fans. some more efficient, quieter, long-living, etc etc for those who modify their laptops for performance.

what would be a good brand or model of fan that you have used that has all the right attributes, and what difference can it make in the case heat buildup?

thanks for your expertise

 

The world of notebook fans is not like the world of desktop fans. You have specific fans for specific boards and chassis. So unfortunately, there's not a diverse market for you to explore. Desktops give you the freedom of choosing different sizes, which - generally - the bigger, the better (in terms of cooling capability). But that's not the case in a notebook; instead, it's "one size fits one".

 

It's so odd considering they all use similar items.

A separate question on the subject of fans.
I want to add a 20mm x 20mm x10mm fan on top of my gpu (gateway w60i) laptop.
It will be a 5 volt fan. I may add a micro on and off switch too.

What do you suggest to tap for power?
The current fan wire or a USB port?

thx

 

I'm going to have to humbly bow out on this one. I'd much rather confess that I'm not sure (especially since I'm not as schooled with Gateway guts), rather than point you in the wrong direction from a haphazardly conceived advisory. I'd also rather tell you I'm not sure than to not respond to your post. I would like to see or hear of your work though if you're able to post screenshots and/or put up a guide on how you go about it!

 

I was going to use this fan. I measured and I am lucky as that fan will fit right above my gpu heatsink. They left it as a normal flat heatsink that is part of the entire cooling mechanism for cpu and gpu.

I think I will tap into a USB port inside for power.

I was thinking of also using this switch

As you can see the fan is tiny so is the switch which I can place underneath just below a bump so then the laptop is on a flat surface it wont be pressed.

Can you tell me why that switch has 6 legs?


It's just an idea for now because I could also put those copper heatsinks on top of the gpu heatsink.
I found a modified bios which allows me to tell the pc what temp to turn on the fan. It's great because it's set for 55c for the CPU which in turns cools the cpu int he process (gpu sits around 60-65) with about 30 browser tabs open in Firefox.
It will throttle the CPU at 71c and shut down at 79c. MY GPU gets hot when I played a game it ran up to 80-90c. I don't play games really on my laptop. MY goal is to keep it as cool as possible so that it will last. Plus I really like the layout of this unit. I press a function key and whamo, all those annoying lights turn off which is great when watching a movie. Even the light on the power button shuts off. I just learned that this chipset (Intel PM965 Crestline) can run 8gigs of ram ddr2 600 or 800mhz. It seems this motherboard can also take the X9100 chip which is a quadcore 3.6 or something like that.
Over time I will upgrade the beast. It currently has an Intel Core 2 Duo 2ghz. This thing has a dedicated 512mb ddr3 ATI GPU 2600hd.

Damn ram chips are $$$ for DDR2.


This Gateway is well deigned. It's in the W650i model series aka M68 series.


***What paste or "glue" do you use to hold those copper heatsinks in place? I doubt it's the regular thermal paste we put on our CPU i.e. Artic 5.

 

I get it. Thermal paste is the best bang I suppose. I've never been a fan of drilling holes. absent a proper airflow modeling program, one's guesswork is more likely to end in turbulence, effectively raising the temp in the case

 

You are putting too much thought into that design. Just remember the HP Nvidia flop because someone did not think about heat.

Heat needs to escape. That fan on top of the cpu or connected to the heatsink module is just there to remove the heat that it is in contact with. It is not some power air mover.

By adding holes you are using natural effects of cold and heat attracting and exchanging energy.

Just remember that heat HAS TO go somewhere.

My HP Dv6000 GPU runs at 40c with 10 Firefox pages open and the CPU is around the same. It idles around 30c. It has dropped in temp. That is without my laptop cooler running or the system fan.

It's up to you but from what I have learned, holy crap these things are just melting themselves.

btw- I am GUEST posted above

 

I use Sekisui thermal tape for my heatsinks.

That's true.

However, I remove the guesswork by basically drilling out the entire bottom plate. It emulates removing the bottom of your bottom plate without the risks.

 

Another thing to consider in notebooks is fan speed settings are controlled by BIOS/UEFI, and cannot easily be adjusted without either hacking the BIOS or using a program like Speedfan or Thinkpad Fan Control (if supported by your system). By replacing the stock fan, some monitoring will be required to determine if the fanspeed settings from the stock fan are as effective on the replacement.
