Interested in inexpensive ramsinks?

I ran across a real good deal on ramsinks at the Overclockers.com classified forums with a guy selling neat looking ramsinks in gold, blue, red and silver, for $0.80 each plus $1.50 shipping. I ordered 30 of them and will let you know what I think about them when I receive them. Since most people here aren't members of the Overclockers forums and since they require 100 posts minimum before you have access to their classified section (and some of the most aggressive action against trolls I've seen at a big forums), I figured I'd see if there is any interest here in getting these ramsinks, with me either acting as the go-between or maybe PM'ing the guy there about seeing if he would accept orders from verified Paypal members here.

Anyways, is there any interest here for inexpensive ramsinks for their ram and mosfets? I have attached some pics of the ramsinks, both loose and attached to ram and mosfets. Since Shorty only allows 3 attachments per post, I'll post the last 2 pics to the next post.

    Here's the last 2 pics.

    EDIT: BTW, these pics are some he posted there in the OCF classies, not mine.

    I'm interested. I'd be interested in like 10-20 of them. I know for sure SM18 would like some of those on her NF7-S :rarr:

    Those are very nice and that's a killer price!

    Yep, I thought the same thing too. Also, I forgot to include in the previous posts that these ramsinks already have a chromerics thermal tape pad on them, which you can use or you can remove it and use AS adhesive to bond them to the ram or mosfet. Personally, I think I would use the AS adhesive on mosfets and use the thermal tape in video ram, in case I had to rma the vid card for some reason. I've seen too many pics of vid cards missing a BGA ram chip from people trying to remove ramsinks.:-/

    I need a BUNCH of those for my parts bin.

    mudd - I'm tentatively interested pending the results of your experience with them. I've seen previous comments that led me to believe that RAMsinks don't do much on the video card RAM, but I know that the MOSFETS on the mobo tend to get frighteningly hot.

    Unfortunately, in my experience I've only ever had one Asus motherboard die on me, and it was the only motherboard on which I've ever put heatsinks on the MOSFETS. :scratch: It was probably my fault somehow or other. :O

    I have an update, guys. I checked email this morning and the guy got back with me and says that he is shipping them out today. So hopefully I will be seeing them by early next week at the latest and we'll go from there. :)

    EDIT: GH, they say that if you use Arctic Silver adhesive that you have to be very careful not to get the adhesive on anything but the silicon you are glueing them to as it is capacitive and slightly conductive; you might have gotten some across the fet legs and shorted them maybe. I think I'm going to order some Arctic Alumina adhesive as it is both non-conductive and non-capacitive. For now I'll probably just use the thermal tape and see how good it is.

    EDIT2: I';ve also read that about video ram, GH, but I've also read recently that the modern high speed ram on the newer vid cards does benefit from sinking them as they run hot when naked. At least that's what I've read because I haven't tried running the ram naked on my x800xt-pe.

    Ah - I likely don't have a modern enough video card to take advantage of it right now.

    I also just used the thermal tape that was on the ramsinks that I bought - honestly, my dead board may have just been totally nonrelated.

    I'm still interested to see your results with the sinks.

    OK, I received the ramsinks in today and they look just like the gold ones in the pics; very nice. I haven't gotten around to installing any yet though, so I can't say how well the thermal tape sticks to mosfets yet. They have plenty of surface area for shedding heat though. The size of the sinks are 15 mm long, 12 mm wide and are 18 mm tall. They are much bigger than the little ramsinks that Epox had included with my old 9NDA3+ board though, which are 10 mm X 7 mm X 10 mm.

    I'll try to install some on my Dual Sata 2 board tomorrow when I shut it down to switch out heatsinks. I'm presently in the middle of some heatsink testing, which got delayed due to the psu I have in that rig not having a hefty enough 12v rail to handle an overclocked X2-4400 running 1.58v vcore. :banghead: I cranked the volts up on that rig to give the heatsinks a real workout. :D

    One other thing; I just can't wait for the /. effect to wear off because trying to post anything in the forums is just terrible.:buck:

    OK, I installed some on my Dual Sata2 board yesterday and no problems were encountered. Since the Dual Sata2 uses small mosfets tripled up for each phase, I was able to place a ramsink across 2 of the mosfets in 4 separate places on the mobo and had to use some small ramsinks that I already had on the 3 that were in real tight areas by themselves. I had no problems getting them to stick to the mosfets and the ramsinks are definitely transferring heat away from the mosfets and are warm to the touch. They are running cooler than the small ramsinks I had to use on the mosfets that are in the tight areas. Looks like they are keepers. :D

    The only problem I see with these could be their size, which is both a help and a curse. A help because it means more area to dissipate heat and a curse to fit them into a tight area on a mobo. However, checking them out on my old NF7-S 2.0 board, they will fit on all 6 of the power mosfets. It's a tight fit on the mosfets between the big caps, but the ramsinks will get in there.

    Nothing that can't quickly be fixed with a hacksaw and vice. About one minute of sawing and two minutes of filing to remove the burrs.

    Yep, that's my thoughts too. BTW, the heatsinks that blow toward the mobo like the BT and XP90 definitely help cool the ramsinks down too, from the air blowing through them. There is a noticable difference in the ramsink temps with a BT on instead of the retail 4 heatpipe cooler of the X2 4400, which is much more conventional in layout.
