Illustrative Guide: Modify your Scythe Infinity mounting system...

[enz660]

well I got the kit, the only thing that you can really use is the backplate. The screws wont fit . Still, im happy I have a backplate. More pressure

This is the kit from Jab-tech that you're referring to, correct?



Why couldn't some plastic spacers be used so that the springs would apply the necessary pressure work? I don't know what the length would have to be but is there something else wrong that I'm missing?

Edit: Probably wouldn't even have to be plastic.

[enz660]

yes I got that kit. Those screws are only threaded at the tip. The scythe infinity mod needs more threads, so they wouldnt reach.

[Omastar]

Well I did the mod finally, and trust me, it's a to do on a BadAxe2 no matter which direction the Scythe is facing, but I tried mine with the longer side facing up toward the PSU like FCG did, and I knocked off one of the blue flame heatsinks, but I reattached it without much problem. Works pretty well, too. I'm at 29-31C idle in TAT at 2.93GHz (stock volts). I'm getting a couple Silverstone 110 cfm fans this week so I'll replace the crappy Thermaltake with them and reposition the HSF so it exhausts out the rear 120mm fans.

I had to loosen the screws from the bottom of the mobo a bit, too, since it was warping a little. I may have to remove a couple washers from the underside of the mobo if I wanna have it even with the standoffs.

[L'enFer]

who knows where to find information about modified mounting of Scythe Infinity on the other sockets?

[Sen5es]

So what is the insulator for? Can i just install it w/o the insulator? I couldn't find any in Home Depot

I dont understand.

You mean the paper (or w/e it is) washer? That's so the screw head/rear washer don't make contact with the board. A plastic washer will do the same thing effectively.

Yeah, a thin nylon washer worked great for me, although I put one or two too many metal washers on the underside of the mobo, but now that my mobo's dead and I have to RMA it doesn't matter. Worked great while it worked, though.

[ragedriven]

the washer insulator is so that the head of the bolt doesn't contact the bottom of the motherboard, these four insulator washers should be the only thing actually touching the motherboard. if you are using a back plate thats insulated this would replace the insulated washers.

as far as other sockets? i think socket 478 needs nothing, good design and mount pressure, socket 775 sucks, bad design.

sucks that the kit didn't work, maybe you could jut mod the kit?

from top to bottom it was like this:

TOP
end of bolt (with enough clearance up to the lowest fin of the scythe to fit screw nut onto bolt, see my first post for sizes, ect.)
------------------
screw nut(similar to wing nut, but smaller turning radius for tighter corners like this, and can still use fingers to tighten)

spring (custom trimed based on distance to cover and compression needed)

1 x metal washer

scythe infinity snap on thingy (minus the removed plastic LGA775 push pins)

(empty space here, should be nothing inbetween scythe mounts and motherboard since it is held up by cpu)

mother board

insulated washer (or back plate)

2xmetal washer (variable, don't let bolt head touch bottom of case)
------------------------
bolt head (this washer + bolt head thickness underneath mobo must be less than motherboard case mount screw thingys)
BOTTOM

--one tip...have motherboard empty and unmounted, put screws washers insulators backplates in bottom first with ends stickin out top, no springs yet, have scythe mounts already snaped in with TIM applied, guide scythe through all four bolts, seat it keeping pressure down on it, slip washer then spring then nut onto each bolt and hand tighten(no wrench will fit in here buddy, go back to homedespot and get right nut that allows proper hand tightening), once hand tightened, use screw driver from bottom to tighten with finger in stop position on nut.

oh yeah, don't forget to lap both cpu and heat sink

[Sen5es]

i thought it was something about not making contact with the mobo. But on the instruction it says x4 don't u need 8 then? 4 top and 4 bottom?

[CHRING]

Very very very nice!! I am also going to try this next week!

I'm currently getting 55 celcius @ full load with my e6600 @ 3300MHz.

Just one (stupid?) question: what is 'lap' exactly (I'm not native-english) and with what kind a tool can you do that?

IHS Lapping
HSF Lapping

just use google next time lol.

[cdelong]

If you order a spare WB mounting kit from DD or D-tek you'll have everything you need for this mod. I did this a long time ago on a Zalman 9500 and it works wonders. I use a set of calipers to ensure equal pressure on the IHS. Just measure from the end of the stud to the knurled nut.

[korby]

Has anyone tried to modify the mounting sistem for AMD? I want to mount this guy on my SD, but I'm afraid to get him "naked".

[L'enFer]

korby, do you think it's really necessary? i tested my Infinity with 3000+ NC and the temps were low enough. during SuperPi 8 Mb calcualtion max temp was 43 degree. room temp was about 25.

[korby]

The temp are good. Well, they'll be better 'cause I'm searhing for some Delta or Sunon fans.
The thing is I'm searching for better benching frecvencies. This SD is specialy picked by XWooDoo (if you guys know him... I mean you should ).

and i use two 80 mm fans of unknown firm that are not very quiet:

[msgclb]

I mounted my Scythe Infinity by removing the push pins and spending $4.38 at Ace Hardware for the following:

4 ea 8/32" machine screws 1 1/4"
4 ea #8 washers
4 ea nylon washers
4 ea rubber washers
4 ea nylon spacers
8 ea 8/32" hex nuts

I neglected to take any pictures. Currently using the Scythe fan but I'm considering using 2 fans.

I was considering purchasing a back plate but this current mounting system looks sufficient.

[korby]

and i use two 80 mm fans of unknown firm that are not very quiet:

I'm searching for something that has >150 CFM. And I'll use two of them in push-pull configuration. And maybe I'll add something something on the sides also.
On daily-use I use the standard fan @ <600 RPM... deeh... silent maniac.

[korby]

Cute, very nice... but I can't find that in here. Romania... I thought we are in EU. Yeah, bull.

[CHRING]

Ok, I did the mod!
Not with springs or anything, just with this:



I dropped about 8 degrees celcius (cpu temp) under full load.
I also lapped my IHS (too tricky to remove it imho), but not any further then 600 grid (read why).
I lapped my HSF just a little bit (only 600 grid), mostly because it's NOT easy with such a big cooler.

edit: here you can see that the outside of my IHS stood up pretty bad!!

right after removing the scythe infinity from the rest:


And here the IHS after a little lapping:

[enz660]

judging from the first pic, either the IHS was very convex, or the base of the heatsink. Personally, that IHS lapping looks unfinished & I would have gone up till 1000grit. I understand how a mirror finish wont give you any real thermal performance gains, but 600grit is VERY rough. My guess is that you can shave off at least 2c from finishing that lap job & lapping the heatsink base. Nice mod though.

[GAM]

Lapping to 600grit is fine, but the objective should be to lap until you have an all copper surface. If that pic is indicative of the finished job, then yeah, do it again.
