Gamestream 700w fan replacement.

[schaffino]

A while ago i purchased the OCZ stealthstream 600w psu. Fooled by the name i thought this psu was gunna be quite. It wasn't. I sent an email to ocz and they told me it was meant to be very quiet and i should rma it. So i did. Postage costed £26 and for my trouble they upgraded me to the model above. The replacement is just as loud if not louder so i think mine and ocz's oppionion on what quantifies as loud differ. Any way, i cant justify spending another £26 sending the psu back again which would make this more than double the cost of my original purchase. Instead i'm gunna swap out the fan.

This brings me onto the real question. I've heard that only ball bearing and the sony fdb bearing fans can be mounted horizontally. Thing is, i've got two scythe slipstreams lying about the place and i'm loathe to spend £10 on a fan when i have two hanging around. So, the question is, have any of you mounted sleeve bearing fans horizontally and did it really make any difference? Should i put the 1200rpm slipstream in or pony up the cash for the s-flex?

and a couple quick questions to add. Does any else get a pretty loud hum coming from there 8800gt when playing games or using ati tool? Also, i have a gigabyte ds3r and a scythe mugen(infinity) cooler. I also have ocz reaper memory taht prevents me from installing the fan on the front.i can kinda just mange to get the fan on in front of the memory but this is a bodge job and worries me a tad. Should i replace the mugen with the new xigmatech sd1283 and given my case (antec solo) would this be a better overall solution anyway. any other ideas.

thanks for your help guys.

Cheers guys

the loud hum could be the fans at full speed, they sound like jet planes lol, also regarding the fans, i have a corsair psu and i think they use yate loon fans, which is barely audible.

While investigating the inside of a spare ocz stealth i have i've kinda answered my own question. The fan inside was a yate loon d12sh-12. A sleeve bearing fan. So apparently ocz think a sleeve bearing fan will do fine

Also, when replaced with the scythe the psu is dead silent. It runs my 1300rpm fan at 960 and then only ramps it up to 1100 with all the load i can throw at it.

Interesting. Was it tricky at all? thats my PSU

Can i ask where the information of the fan make was from. I have loked into this for 3-4 PUs and this information, besides stripping the PSU down, is nigh on impossible to come by.

The mod is dead easy to do. The screws come out, the top comes of and the current fan is a 2-pin connecter. i pulled out the connecter, cut it off from the stock fan and attatched it to my new fan. the way i did this was easy, i removed the sleaving on the end of each wire then twisted the corresponding wires round each other then covered it up with some sleeving from an old artic cooling fan i have. Gaffa tape will work though, i. I even left the rpm connected so i could thread it out to my mother board. i've left of the grill as i dont really see a need for it (in a tidy case) and i used sillicone fan mounts to attatch the fan.

Out of curiosity i've actually installed and tested it with an s-flex and this worked fine, but it seems to me that this fan doesnt cool aswell as the slipstream as even though its got a lower max speed, 1180 its seems to ramp up to about 1000 at idle, meaning the psu is running hotter, so i dont think it blows as much air as the slipstream or copes as well in this situation. though it supposedly will last a lot longer.

and to the person asking what fans are used in there psu's. Most good reviews will look inside and tell you what fan is used. Though i found that my ocz stealth didnt have the original ball bearing fan that the interviews had found.

Cheers for that.

you really need to watch what you touch inside a psu there are alot of capacitor inside that could store a large voltage/amp so be carefull, the case are there for a reason

[schaffino]

well obviosuly once its been unplugged you turn it on quickly which'll discharge everything. you may notice the fan spin a little. If your feeling extra safe you should leave it for 20mins. I must admit i've given myself a pretty good shock a couple times but i'm just reckless. I'll have to keep an eye on that when i get my pacemaker fitted

Yeah, last time I got electrocuted was from a Coke machine in France.

I have no desire to repeat that experience (though French nurses are HAWT) so I'm going to stay out of the box with the sticker reading "Trained personel only"

Congrats on fixing yours yourself though...
