Re: [Discuss-gnuradio] fan replacement for usrp1?
Thanks Robert, I hadn't ever noticed it getting hot to the touch, but I haven't tried running it w/ no fan & top on either… Best, Mark -- mark.cetilia.org | mem1.com | reduxproject.com On Oct 19, 2011, at 10:40 AM, Robert McGwier wrote: > Top on.

Re: [Discuss-gnuradio] fan replacement for usrp1?
Top on. Fire up the fastest card you have (widest band signal you can process) and put your finger on the FPGA. It is cool. If the oscillator in the USRP1 were most stable and accurate, it might make some sense but it just doesn't in my opinion make sense so I disconnected them all in my USRP 1's.

Ah good, glad to hear it's not just me… Do you run it with the top on or leave it open?

Yes I have. I disconnected it. In my opinion, it is overkill for anything going on in a USRP1.

Re: [Discuss-gnuradio] fan replacement for usrp1?
ok so this has been working just fine at home, but i am actually beginning to use the usrp in performances fairly regularly, and you never know what might happen in such situations… so just to be on the safe side, i'd really rather replace the fan. unfortunately i'm not having much luck finding the exact fan that came with it in stock anywhere, but i've found a possible replacement that seems to basically meet the specs: http://search.digikey.com/us/en/products/F410T-05LC/563-1130-ND/1165524 the only thing that doesn't match up is the air flow— it's rated at 3.9CFM rather than the cooltron's 4.6CFM. anyone have a clue as to whether or not this would be enough of a difference to cause concern? otherwise the specs look fine, and it's supposed to have a noise floor of 12 dBA instead of ~21, so we're talking roughly half the volume… could really make a difference. thanks in advance, mark p.s. does anyone else have this same issue or is it just me? i'm wondering if maybe it's just that my fan is defective… 20 dBA should be "a whisper" and mine seems to be much louder than that. -- mark.cetilia.org | mem1.com | reduxproject.com On Oct 9, 2011, at 2:04 PM, Mark Cetilia wrote: > ah yes, i feel it coming back, slowly. > thank you :) > > m > > -- > mark.cetilia.org | mem1.com | reduxproject.com > > On Oct 9, 2011, at 3:39 AM, Mike Jameson wrote: > >> Hi Mark, >> >> If you take off the top of the enclosure on the USRP1 then you don't even >> need a fan! >> >> Your sanity should then return :) >> >> Mike >> M0MIK >> >> >> On 9 October 2011 06:43, Mark Cetilia wrote: >> wondering if anybody out there has replaced their usrp1 fan with something a >> bit quieter? >> i find myself listening to its incessant whine many hours a day, and it's >> starting to make me a little crazy— >> especially when i am trying to listen to subtle details… anybody have a >> suggestion for a decent replacement? >> >> cheers, >> mark >> >> -- >> mark.cetilia.org | mem1.com | reduxproject.com >> >> >> ___ >> Discuss-gnuradio mailing list >> Discuss-gnuradio@gnu.org >> https://lists.gnu.org/mailman/listinfo/discuss-gnuradio >> > > ___ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Re: [Discuss-gnuradio] fan replacement for usrp1?
Hi Mark, If you take off the top of the enclosure on the USRP1 then you don't even need a fan! Your sanity should then return :) Mike M0MIK On 9 October 2011 06:43, Mark Cetilia wrote: > wondering if anybody out there has replaced their usrp1 fan with something > a bit quieter? > i find myself listening to its incessant whine many hours a day, and it's > starting to make me a little crazy— > especially when i am trying to listen to subtle details… anybody have a > suggestion for a decent replacement? > > cheers, > mark > > -- > mark.cetilia.org | mem1.com | reduxproject.com > > > ___ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio > ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] fan replacement for usrp1?
wondering if anybody out there has replaced their usrp1 fan with something a bit quieter? i find myself listening to its incessant whine many hours a day, and it's starting to make me a little crazy— especially when i am trying to listen to subtle details… anybody have a suggestion for a decent replacement? cheers, mark -- mark.cetilia.org | mem1.com | reduxproject.com ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
