    i am trying to find different ways of cooling my wrt. i have recently put it in my atic and gets hot up there since it is alomost summer time here in the US. i have 2 wrts stacked one on top of the other. and i put a thermometer between the 2 wrts and they can hit about 100 degrees fahrenheit . i put a fan on it but i have to leave it on all the time. funny thing is that i would lose wifi, i would not see the ssid of the wrt's when it gets really hot.

    does anyone have any suggestions on how to cool it better like paiting it
    white. or something like that.

    Don't paint it. I would try drilling some more ventillation holes in the cases and using RAMsinks.

    You could also try not stacking them which should help a lot too. You could also run them bare, without the case covering them.

    EDIT: If you get the RAMsinks, you would put them on the memory and other chips.

    Drill some holes in it, don't stack em ontop of each. Also have you tried adding a fan to each of them?

    Look at my guide I think thats the best way to cool them!

    cool thank you for your replies. i think that i might drill some more holes in it. as for staking them it is not really a option were they are kept is a small space and need to be stacke. i think that the ramsinks are a great idea and i might even try them. do u know if radioshack or best buy carries them.

    You can get them online - the memory heatsinks + cpu heatsinks + termal glue paste for under $20 on eBay.

    This is what I have done. Produces a-lot of airflow/cooling.

    Photo 1 Shows the heat sinks.
    Photo 2 Shows the top of the router. The 80mm fan and fan speed control.
    Photo 3 Shows the hole cut out from under the fan, to allow full air flow.

    is that fan blowing in or out?
  9. ybbmadysu

    Its blowing in. From under the router I can feel a-lot of air flow. seems to work great.

    In the begining I left the top case alsone, but the flow wasnt that great. After cutting the top off it received much more.
  10. jagboy

    jagboy Network Guru Member

    you should have it blowing out. since heat rises. the fan could help carry it out.
  11. ybbmadysu

    ybbmadysu Network Guru Member

    That was the orig idea, but here it gets really dusty/dirty. I have to clean the comp every month cause that issue.
    I decided to have it blow in for 2 reasons, 1-to have a large air filter (better flow) and 2-I put the cable modem under it, keeps them both cool.

    jagboy Network Guru Member

    i have me routers stacked. and the router on top has the fan. which blows out. but it keeps both cool too.
  13. ybbmadysu

    ybbmadysu Network Guru Member

    What do you do about dust (is that even a problem for you?)?

    I may try that on my next one, I bricked the one I have now on friday of last week. cant fix it.
  14. jagboy

    jagboy Network Guru Member

    well i do have dust problems.like on the fans and stuff. but that is not a big deal .i just take a dust cloth and just wipe it down.

    that is one reaons why i dont have the fan blowing into the router, wont dust get into the router.
  15. ybbmadysu

    ybbmadysu Network Guru Member

    I checked it on friday, it had been left closed for a few months. it really wasnt dirty, the filter that I use is actually window screen material, not the metal kind, its plastic. I just folded a piece 4 times and taped it on. Every few days we just clean the filter w/ the vacum. worked out great. If you saw the photos you should have seen that I taped it on with a nice bubble on top, did that just for extra air flow and to keep it away from the fan blades.

    jagboy Network Guru Member

    how do you keep it up and alway form the fan bdlades. i would imagine that the fan blades would usck the filter closer.
  17. ybbmadysu

    ybbmadysu Network Guru Member

    naw, in the images you can see that I put the filter on in a bubble to keep it away from the blades, and on the side of the fan is a fan speed control (low-med-high).
    Totally works great.

    EDIT: Look at this photo

    were did you ge the fan. and how loud is it.
  19. ybbmadysu

    ybbmadysu Network Guru Member

    The fan came from newegg.com click here it was cheap, but it works.

    its really not loud, since it is connected to a speed controller I can turn the speed down, that helps to make it really quiet.[/url]

    aah ok thanks

    Blowing in should actually provide better cooling performance than out. The overall airflow should always err on more in than out in computer/electronics equipment.

    if you remove the front vinyl from the router you will get dramatically increased airflow rates leaving the router. even with the from vinyl removed and holes drilled into the sides, my router still pushes a load of air out of the bottom of the router.

    It really doesnt matter much if you pull or push the air or where the fan is mounted... Almost any fan will do a fair job of moving the air within. Really.

    I chose to mount the fan inside to keep a cleaner look but you dont have to.

    Crappy doodle to illustrate what I mean:

    Cenreyn79: if you mean to imply or conclude that there is a restriction to airflow and gained by providing another exit, let me suggest that you flip the fan over.
  24. GNandGS

    Other than some of the newer cases with a CPU duct to the outside, most case fans are setup with an in AND an out for airflow (even with just one fan). Prior to that, there was only ONE fan mounted internally in the power supply.

    While actuall "vacuum" is never acheived, or even close to it, when you pull air out from one side its drawn in from the other - it has to. In this way, for the linksys routers, it doesnt matter how its mounted. Air will flow. I cant see anyone requiring additional cooling performance after a fan is installed.

    You dont cool things off by adding "cool" but instead remove the heat.

    I think its easier to draw air in with an internal fan.

    Sorry guys! Didnt mean to sound rude. Modding for modding's sake is OK! Ditto for experimenting!

    It is NOT "my way" or else.

    When you are trying to suck air out of the router, you will lose suction if there is any hole, no matter the size. But if you are forcing the air in, any hole would be acceptable.

    hum, im thinking of installing a fan, but reading this, im still not sure if i should have it blowing in or out. iv seen some ins and some outs. my wrt54g is placed on its side, with the antenna and ports on the top. this might change the cooling system, as heat rises.

    what would be recommended?
  28. Cenreyn79

    Cenreyn79 Network Guru Member

    on the top you say? care to send us a photo of it?
  29. sven007

    sven007 Network Guru Member

    lol, hum. instead of having the bottom placed on a desk like normal people, the bottom of mine is against the wall. the 4 legs are attached to the wall, and the antennae are pointing upwards, the antennea is not bent at all if you were to unscrew it.

    [edit] u know what, nevermind lol. the way i put it shouldn't change anything. in or out, thats really the main question.

    sven007, if you're not overclocking the router or boosting the transmit power past 84 mW then you probably don't even need to install a fan. If you are doing those things, then i'd suggest heatsinks on the chips first. Only problem with that is, how do you keep them on the chips when you have your WRT on the wall as you mentioned? That I don't know, but I'll assume that you'd have to be creative in coming up with a solution.

    As far as which way to install the fan. If you set the router on it's feet then it only makes sense to me to have the fan blow air out of the router. The chips generate heat, heatsinks sit on top of the chips and the fins on the sinks spread out the heat and of course, heat rises. So, if the fan is above the heat, which is above the heatsinks, which are above the chips, then the fan should blow out, lol.

    However, don't trust me. What do I know. I wasn't sure which way to do it either, but I took a look at some other pieces of electronic equipment that have fans and...my laptop has a fan that blows air out, my Playstation 2 has a fan that blows out and the power amp to my Marshall Jubilee 300 bass rig also has a fan that blows air out. In conclusion, I figured that it's probably not a coincidence that the experts at Marshall, Gateway and Sony all have their cooling fans blow air out. This will also reduce the amount of dust that can accumulate inside the hardware. With all that being said, i'd now suggest that even with the way you place your router, to have the fan blow air out of the WRT. Good luck and have fun!

    will do. and im looking for heatsinks atm, the fan i have and ill add just to help the heat move. thanks a lot :)
