[build] EKGA STH-10 : A 900D Rebuild - Page 20

OK, time for the CPU back plate mod guide. This is actually much more simple than I had originally thought.

DUE CREDIT: MehlstaubTheCat

Stuff needed

1x Dynatron G199 (lga 1366 variant, 2011 MODELS WILL NOT FIT)

4x M4 45mm screws, you could also go with 50mm long screws like i did, but you are GOING to need extra nylon washers to make it properly fit. This guide is written with the assumption you will be using an EK supremacy block, so if you are not, you need to find out what size your fittings are & change the screws accordingly.

8x nylon wasyers

4x copper washers

1x big old sheet of thermal pad. I recommend FujiPoly, it is some hard core stuff. CHILL IT BEFORE USING IT (it's that soft)

if you want to lap the back plate:

sheet of 400 grit, sheet of 800 grit, sheet of 1200 grit, sheet of 1500 grit, sheet of 2000 grit, sheet of 2500 grit (I couldn't find 2500 locally) FrozenCPU does sell a lapping kit for ~10-15$ last, some sort of rubbing/polishing compound. I used my dremel & the provided compound/head to polish it out.Lapping is pretty straight forward, sand it down, sand it some more, sand it even more, keep sanding,


ok, so first things first. Remove the stock screws from the dynatron. Try not to put a giant gash in it (like I did) The end result should look something like this.


Next, remove the black plastic lining from the LGA 1366 bracket, clean thoroughly with alcohol or ammonia.

Next, cut out a piece of thermal pad = to the size of the back plate, & place it on. Make small slits with a razor so that it fits over the bolts, push it down, & rub out all of the air bubbles.

Next, (if you want, might as well) you need to take the locking mechanism, remove the black plastic, clean it, & cover it with thermal pad, like this.

OK, now that this is done you can put the motherboard back together.

It's much better to cut the piece of thermal pad too big, you don't want to cause any shorts. After this, take something soft & cut the excess pad down to size.

Next you want to start filling in all the holes so that it ever so slightly protrudes from the back plate.

Should look something like this.

OK, now comes the fun part. Painting on the thermal paste. I went with PK-3 for this process because it's non-conductive, is REALLY thick, & really sticky.

Next, you want to get your screws ready.(note that I used 50mm long screws, so I had to use extra washers to get things right)

Now you want to slide them onto the dynatron.

Now it's time to mate it all together. Slide put the dynatron on it's back, pickup the motherboard and slide it through the screws. Once you have done this you can slide the water block on, lock everything down, and boom you are done!

So, in club titan this after noon I stumbled across a post from Skyn3t. It contained a video from West Coast Mods of a semi-cheep rad flushing unit. I went to home depot & got all the stuff needed to put this together. Due to them not having EXACTLY the right stuff it cost a bit more than it should, but what are you going to do you know? I'm sick of derping around, so it's time to step up my game. This post will be a small guide on how to build your own rad flushing unit. SO, here it goes... Warning: Spoiler! (Click to show)
SUPPLIES:

A.) GE Whole House Filtration System: 40.00$

B.)Some sort of CHEEP submersible pump. Some Home Depot's carry cheaper units than others, should be able to find it for 40$, I had to pay 80$ because i'm too lazy to find a cheaper unit.SOME CHEEP POND PUMPS WILL COME WITH PLASTIC BARBS, WHICH WILL SAVE YOU EVEN MORE MONEY.


OK, so here is where it becomes a slight pain in the ass. As you can tell the fittings for these things are huge, & most hardware stores are not going to carry a single piece to go from 1" to 1/2 ID. So, I had to get multiple fittings to link them together properly.

For the Pump:None of these fittings are needed if your home depot simply carries the proper 1inch to 1/2 ID plastic fittings
1x) 1" x 3/4" PVC bushing: This will go into the main thread of the pump, & allow you to connect a smaller bushing to it.


1x) 3/4" to 1/2" PVC Bushing: This will sit inside the first bushing, and allow a proper barb to be fitted to the pump.


1x) 1/2x1/2" Brass Adapter barb. This will sit inside the first to bushings to allow a tube to be connected to the pump


For the GE Whole house filtration unit:

2x) 3/4" x 1/2" Brass hex bushing: This will go into either side of the filter unit.


2x) 1/2 x 1/2" Brass adapter barb.


1x) Home Depot Bucket.

3x gallons of distilled water.

10x feet of cheep 1/2ID hose to link it all together. It should be on the same isle as pretty much everything else.


OK, that's the part list. I would highly recommend some hose clamps & some nylon tape. Also, if you don't happen to have 2x barbs for your radiator, you might want to find some, or just use w/e fittings you normally use. Bards are easiest for this get up. So, you hook it up just like a loop. Pump(sitting in bucket)>>Rad>>Filter>>bucket. This is pretty much the most expensive way to do it, I had to do it this way due to lack of proper supplies. I have added in notes on how to save money. Should be able to get it all done for under 100$ if you take your time picking out the parts.




Remember, the #1 pump/block killer is radiator gunk.

Well, after reading this I decided I felt I had to give it a go myself. Thanks for the idea. I did all my shopping at amazon and ebay, and this is what I came up with. I think I spent about $70 in all. I hope I didn't leave anything out (other than the 5 gal bucket I already have) or worse, ordered something that isn't going to work ...

Edit:
Awww, I just noticed the pump I ordered from ebay only comes with a 3/8" fitting. I had priced the same pump elsewhere for ~$6 more before I found it on ebay, and it said it came with 3/8", 1/2" and 3/4" fittings. Now, assuming the ebay listing is correct, I'll have to figure some way to attach my 1/2 hose to that 3/8" barb. Hmmm?

- - - - - - - -
Late edit:
Turns out the other pump I saw with the assorted fittings was a 550 GPH pump of the same brand and it was ~$10 or so more. I may just go ahead and buy it too. I'll probably find another use for the 400GPH pump.

Late - Late Edit:

To make the 400 GPH pump work, I'd have needed one of these (and a short piece of 3/8" I.D. tubing):

LEAD Technologies Inc. V1.01

But instead I just went ahead and ordered the larger pump I should have gotten in the first place, so I did wind up spening over $100, but I have an extra pump I'm going to do something else with. :

I got my set up running. How long did you let yours run for?

about 30-45 minutes. Until the water was very warm.

If I had a camera good enough to take pictures of the filter I would do so, but since it's not working out well enough to show said pictures I can only give a verbal analysis. After flushing 3x rads, (2x 480s 1x 360) I have what looks like about 3/4 of a gram of sand size & larger particles in the bottom of the filter. Chunks of black, grey/silver & copper. When looking closer I can see TONS of black/silver/copper flakes stuck through out the entire filter, so I would say this process was a major success.

Did some one a favor @ work by letting them pickup my friday shift, so I now have a three day weekend. So, now that my new blocks are in i'm hoping to get 99% finished this weekend.

Good luck finalizing the project thumb.gif

Hi skupples,

I like the little "How to make a Backplatemod" nearly the same as i do, little difference here an there, but the end result is the same.
Congratulate you on your first Backplatemod. thumb.gif

I had to mention you in the post for due credit, some on else on OCN has done it as well, but I can never remember who he is. =(

The only thing i'm worried about is lack of pressure between all the pieces, cpu/waterblock/back plate. The 50mm long screws were just waaaaaaaaaaaaaaaaaaaay too long, so I had to use 6mm worth of washers. I'm going to hit up the hardware store for replacements before I get to work tomorrow morning.

got my copper blocks in today, & hopefully EK will approve my RMA so I can get my 400$ back.

some one tried telling me my blocks were simply discolored, but cleaning just made the corrosion look even worse. mad.gif(can actually see copper on the CPU cooling plate)

That's good to hear. I hope I have anywhere near as good results with my budget-version I totally stole the idea from you. devil-smiley-019.gif Thanks again! wink.gif

Did you try shaking/tilting/flipping the rad around any while it was pumping, or reversing the direction of flow, or anything like that or did you just let it run like that, and for how long??

& i stole it from majin ssj Eric who got it from west coast modOrz... I had ports facing down is all. Stuck the rad in a clay pot.
