WRT54GL heatsink for processor?

    Can someone point to a heatsink that works for it? http://www.newegg.com/ The reason for this. I recently OC the cpu and when I feel it on top. It feels a little to toasty for my taste. And this is in cooler weather right now. I would imagine it would get much hotter in the summer. Other then that. The router has been 100% stable for me. Maybe I am just being paranoid and the heatsink is really not needed?

    I think Toastman has some pretty extensive experience with running overclocked without heatsinks without issues. Can probably find some of the details by searching this forum.

    Thank you both. I have seen Toastman's posts about OC the WRT54GL. He has had no issues that I know of. But I just don't like how warm the top feels. Maybe what feels cool to him is hot to me. Or the other way around.

    I wish he showed the finish work. How many heatsinks do you think are used on the chip? They look to small for just 1 of them to fit. But looks can be deceiving. I am still looking into this and might not even put in a heatsink. But if I decide. I wanted to know what works.

    So if we add the heatsink, are we able to overclock it to 300MHz?

    Sarcasm much? :rolleyes: Lets be realistic here please. :)

    No I wasn't sarcastic. Cos the WRT54GL can already be overclocked to 250Mhz now. So if we are to add in heatsink, I do expect it to be able to be clocked to 300Mhz at least.

    My apologies. :) I don't think anyone has reached 300MHz yet. I know there is a mod that a person made to make it go past 250MHz. I think he got it up to 275MHz and it became a bit unstable with cooling. Think he just had a heatsink on it. I need to find that mod for more info again. Found it. http://www.bitsum.com/openwiking/owbase/ow.asp?WRT54G Article is some what old though and has not been updated.

    Yes, it's possible to clock most chips rather higher than 250 - 275 or even approaching 300. But it isn't as easy as you might imagine. And it's pretty debatable whether it's really worth the trouble. The article isn't updated because - what's to update?

    Re. a heatsink - any good computer store should have what they might call VGA heatsinks - used for cooling onboard graphics chips and North/Southbridge. These things are worth just a few cents, it's usual to buy 10 at a time ! Buy some heatsink grease at the same shop.

    Linksys actually shipped a lot of the wrt54s with the chips running at frequencies lower than they were built for. If i remember correctly 250mhz is actually one of the cpus frequencies which would mean it's not technically overclocking i.e. it shouldn't be needing a hs. Still, at that price there's nothing wrong with trying :)

    Thanks again everyone. I have decided to roll with out the heatsink. If Toastman can run hundreds without a heatsink and at 250MHz. Mine should be fine. Like I said before. Think I am just being way to paranoid about it. It has been stable for the 3 days it has been up since the OC. It has also given me a very nice little performance boost that was needed with my 25mb/3mb line. My next router will be the Asus N-16 with Victek firmware.

    I'm using my WRT54GL 1.1 200MHz@250MHz (stock Tomato) without a heatsink for over 1,5 years now (including a very hot summer with 35°C+) and had no problems. It's not even remotely hot under load.
