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

[s1rrah]

Can i also make a home-made backplate? I thought making one from (don't know how you call it in english):

In US. We call 'cutting board.'



Seems that would not be rigid enough. You couldn't obtain as high of a pressure with that as you could with metal. Too flexible.

I could be wrong, though ...

[intel_478]

In light of the previous posts about the cutting board-debacle () I cancelled the zahlman backplate because it's made of plastic and I don't think it wil be strong/good enough, so now I'm going for the Thermalright backplate mentioned earlier in this thread.

I wonder if the Scythe Infinity heatsink is actually bigger or smaller than my current NB-CoolScraper (socket 478) heatsink

By the way, about the logo of this forum: if the word "Max" was placed more to the left it would make more sense (no offence)

[deees]

I think this is all going to work and I hope to be able to post 4 GHz screenshots soon!

I wouldn't recommend the ZALMAN backplate. I tried it on my bolt-down mod, (back at post #146), but found it too flexible. I switched to the Thermalright, the only issue I have with it is related to the thumbnuts I use to tighen the mounting screws. I needed to add spacers in order to allow me to get a grip on them. This is only because I tighten my unit from behind the motherboard. I'm sure the Thermalright is stiff enough to crush the LGA775 socket if I really wanted to.

@ deees:
I think it's very true what you say and, as I mentioned above, I have already switched the zalman for the Thermalright backplate.
But a few things 'concern' me:

Since I don’t know how to properly calculate or measure the required 18 –70 lbf preload needed to protect the solder joints in the processor socket, I’ll assume that Scythe factored that into the clip. If you're interested in increasing the pressure on the HSF/processor interface, you could use thinner spacers.

Where are those spacers situated?
And do I need to drill out the holes of the TT backplate if I use Alphacool's 4M screws?

And.... Now I took another look at you post, I am still very impressed by the very strong clips you made. Any chance you want to make the same for me? Of course I will pay you

[barzi]

If I want to mod my infinity, I want to use a backplate. Which is better?(e6600)

Coolermaster:
http://ecd.coolermaster.com/english/...ylist_ebp_n775

Thermalright(this is a backplate right?)
http://www.azerty.nl/producten/produ...5-rm-clip.html

Which is better? the CM one is only 1 euro, the TR is 6 euro. Which is stronger/better for this mod(s775)?

So the cutting board is to flexible?
What about these 2 backplates? Is the thermalright one a backplate?(because it's called RM clip)

Are those just the same? Because the CM is only 1 euro, and the thermalright one is 6 euro.

The spacers I was referring to in the version back at post #120 were the ones between the motherboard and the HSF mounting clips. The white part of the Intel pins are about 0.1” thin, and I cut my spacers to the same thickness. The logic was that the clips provide the necessary preload when compressed to that distance from the motherboard.

In later versions, I replaced the spacers with springs to maintain the preload while permitting me to increase the pressure by tightening the mounting screws

And do I need to drill out the holes of the TT backplate if I use Alphacool's 4M screws?

Yes, the Thermalright backup plate has 3mm threaded bosses.

And.... Now I took another look at you post, I am still very impressed by the very strong clips you made. Any chance you want to make the same for me? Of course I will pay you

Unfortunately, there is an awful lot of handwork needed for me to make these, so I’d end up charging you more than you’d want to pay. Also, I’d be reluctant to sell them since they could potential cause damage to other expensive computer components and I wouldn’t what to deal with the potential liability. (Don’t you just love the new litigious sociality we live in)?

Having said that, I’d certainly be happy to assist you in making your own. They’re time-consuming to make, but not terrible difficult. The tools I used were inexpensive and pretty easy to find. (Although this project has really gotten me thinking about buying a small milling machine). If you decide to try this and have any questions, let me know.

The Thermalright is a back plate made of stamped steel metal. (The same basic plate that is used in a lot of other HSF's.) I can't speak for the Coolmaster one, (it should be stiff enough if it's made out of the right alloy), but I know that is Thermalright will definitely work.

[intel_478]

@ deees
I believe you right away and I think I won't be able to make better clips than shipped with the Infinity so I'll just use those. But thanks anyway.


It's a bit disappointing that the Thermalright backplate doesn't have 4M holes, especially when I tell you that I paid €8,90 for it..

Ermm, I was wondering if anyone here actually used the Scythe Universal Retention Kit?

If so, can anyone give any thoughts on using this "genuine" mounting kit instead of a modded one?

WOW! just what i was looking for!

[musa]

Unfortunately there's a copper spacer that seems very dubious to me... that's why I need experienced info on this.

[s1rrah]

To all my Scythe Modding comrades!

I offer you an Inspirational Photo(tm):

...

Pressure modified this Infinity about 5 months ago; when installing the pressure mod, I discovered my springs were way to weak and flimsy and so, thinking fast, I cut a bic ball point pin into 1/4 inch segments and used these in place of the springs.

Bent my motherboard all to hell but finally got it mounted.

I haven't dismantled it since. Scared to, in fact. It's working so good.

Anyway, when I get a new cooler, and finally get the nerve to break this thing apart, I'll take some photos of my Ghetto Pen Mod(tm) and post them here so as to possibly humor you all.

But it works, so ...

Has anyone tried to increase pressure not by applying more force at the bolts, but by applying a wedge between the 2 prongs and heatsink slots and keep the intel plastic plugs?

[intel_478]

@s1rrah

Are all those big fans close to each other really necessary?
My plan was to put the 120mm fan that comes with the Infinity on the back of my case and leve the heatsink passive.
Because there is also an 120mm fan of my powersupply above the cpu.

Can anyone tell me (or gues, based on some experience) if I will be able to oc my E6600 to 3.6GHz (stable) ?

One of the concerns with the Intel design is the ability of the plastic pins to handle even the dead weight of the Infinity, (being 2x the design load). Adding to that any additional pressure would make me nervous.

There's also going to be a limit on how much pressure the metal clips themselves can handle before they snap, (although providing support between the motherboard and “feet” will reduce the rotational torque that probably causes most of the failures).

Just be careful if you try to increase pressure using the standard Scythe clips without spacers between the motherboard and the clips.

Why don’t you check out your local hardware store for some aluminum angle, (L-channel). The stuff I used was ¾” x ¾”x 1/8 “, (or 19x19x3mm). That would give you enough material to make several clips, (including any mistakes) and it ran me about $5USD. I made the cuts using one of these:

…using a 40 TPI blade. The holes were drilled using one of these:

http://www.acehardware.com/product/i...entPage=family

You could start with the bracket:

The only “critical” dimensions are the hole locations and the clearance between the horizontal “tabs”. I recommend that you start with the holes, and then work on removing the excess material. The finishing work is just filing and sanding. Even without making the braces, you could have a usable pressure-mod.

It's a bit disappointing that the Thermalright backplate doesn't have 4M holes, especially when I tell you that I paid €8,90 for it..

Just drill-out the bosses and secure the screws with nuts.

The Heatsink fans (two FM121's) are in a somewhat standard and normal push > < push configuration (both blowing IN to the heatsink fins); the rear case fan, which is also somewhat traditional is actually flipped around and is bringing room air straight into the Infinity fan; similarly, in the front of my case, I've mounted two more 120mm fan's to blow room air into the other Infinity fan.

Works so good man.

I tested everything, single fan, dual fan's in push > pull > ... case fans in a more traditional intake/exhaust scheme ... and the below configuration seriously beats anything else I've tried.

My Armor case is basically one big mesh box, totally perforated and so using mostly intake fan's works rather well:

Here's how it's setup:

(BTW ... 3.6ghz will depend on your cpu/mb/ram ... properly mounted, the Infinity is fine for 3.6ghz; I run at 3.8ghz sometimes and temps are fine)

Just a thought ... you won't be happy at 3.6ghz running the cooler passive ... it's a so-so passive cooler but not great or anything; certainly not on par with running such as the thermalright's passive ...

You don't have to run the fan's that fast; mine are usually at about 40% of their rated speed; 1300 RPM's or something ... adding two fan's really lets you cut the RPM's back.

[intel_478]

Thanks very much for all the excellent information and advice people!

I made a quick picture of my current airflow situation. (see picture below)
I will look up the cfm values if needed.

I like the thought of lower rpm very much, because I'm kind of a ultra-low-noise-freak.
Therefor all my fans are currentle max. ~20dB and avg. ~15 dB (automatic digital temp. monitoring fancontroller)
I have read that the Infinity comes with a 23 dB fan and I was hoping to get it operating at ~19 dB.
<edit> I just bought 2 extra low-noise 120mm Scythe fan's </edit> for a push-push intallation on the Infinity to make the 3.6 GHz possible.

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

this is the ninja mounted to my board with the TT bolt-thru kit. i put washers between the spring and the mounting clips to apply more pressure.

That looks like the perfect mount for the Infinity. If the springs work for the 120 Ultra, the proper compression should fall within the same ballpark for the Infinity with the added washers. The springs for the mod on the first page are completely compressed already so they may not be strong enough.

How would you turn those screws? The infinity blocks the top of those screw heads. Can you just push down, squeeze the bolt head with your fingers and turn? Or can these screw heads only be used with the Ninja because the opening at the corners allow a long screwdriver to fit through?

[s1rrah]

Can you just squeeze the bolt head with your fingers and turn?

Try it. You'll bleed for sure.



You won't be reaching under the infinity to hand tighten regular screws ... have to go with gnurled knobs or use nuts and a wrench.

I went with the wrench option, myself ...

[BobHarris]

How about placing a hex screwdriver tip over the screw to turn it?

From your dwg the holes are 72mm apart on a LGA775 board in both directions right? What would the spacing be on a 478 is it the same?

Sorry if its a dumb question. I think I'm gonna have to make a backplate myself I cant find one anywhere in UK.
