Fuzion CPU middle to Top Block gap

[Jedda]

seems like they need to sell a nozzle kit with a gasket or flat disc to fill-in the gap

I would pay in a heart beat....

Danny are you listening....please

Yeah, it looks as if that might've been the original idea.

I read through that and didn't catch your comment the first time about the leaking...you were right!

Anyhow. For fun, I performed the Uber High Tech....."Play-Doh" test on this gap to get a better idea of thickness needed with an assembled block.

By the way this only works with ORANGE Play-Doh and no immitations will work the same!...

Almost exactly 1.0mm of gap is there per the official "Play-Doh" testing lab...(And don't tell my son about this!)

If you only want to seal, you need some softer material just about 1mm or thicker, and to bow....something thicker than 1.0mm..

After reading this thread I added 1.6 mm thick Oring. I did not see large bowing effect from this small Oring. This is probably due to the 1mm gap that already exists, so the compressed oring is just filling this space...But my temps improved 1.5 degrees.

So this means that the Fuzion can be improved without bowing and with out adding jets. So if you are not someone who want to bow his base they can get better performance... If I had a thicker O-ring I would get the bowing effect and probably have even higher improvement. How thick is O-ring you are using. (I did not get o-ring from barb, I have a metric O ring kit and this is the only size that would fit)

That's great to know...thanks!
I gained very roughly 3C from my washer which is probably a little over 1mm but hard plastic and did seem to bow only very very slightly, but this was after I had a nozzle.

Adding a nozzle will increase resistance and make the leaking problem even worse, that's probably why I saw the bigger improvement.

So it sounds like a nozzle and thin o-ring should to be worth about 2-3C maybe more..

[dinos22]

hmmm i donno about your testing methods there. Actually i am a little disappointed

the correct colour of playdoh used should have been the following



my daughter's got plenty of it around if you need some i can send it over

[jerrydog]

I used a PINK O-ring!!!

[aiya]

don't mean to thread jack but didn't feel like making a new thread and i did a search and didn't find anything. anyways, can any of you guys with Fuzion blocks tell me how long your mounting screws are? thanks.

[carholmes]

The screws are around 6mm long.

My plastic was just a sheet, and I used a special drill (Tiny center spade and outside edge cutter) bit to cut out the ID hole and scissors to cut around the outside.

thanks

Guys does Lowe's, HD or Ace sell small O-rings we could use?

[newls1]

Play Doh is the best stuff. I remember using Play-Doh to help me find my piston to valve clearance back a few years ago on my drag car.. Great find!!!

[Martinm210]

Hehe...So many uses that Play-Doh has..

Anyhow, I saw a few o-rings in the bolt bins at my Home Depot but there's not a huge selection. We have another home improvent store locally though that has a big o-ring box I saw, not sure what Lowes has.

It may be an easier find at some automotive type stores. Anyhow, I'll go searching today and see what o-ring options may be out there.

I think that 1.6mm metric o-ring would be perfect for a non-bow or very litle bow, and one of the thicker types for a more substantial bow.

[jerrydog]

Yes I agree 1.6mm would be the best thickness. I think you can buy them at Mcmaster....but not sure the minimum you need to buy

[MaxxxRacer]

LOL, this is why i used the oring in the first place when i did this 5 months ago. It was to stop leakage not to bow. Would be neat to see something that would stop leakage but not alter the base at all and see what happens... like a neoprene gasket or something.

i dont like neoprene in waterblocks. if you remember the TDX and RBX, they both had neoprene gaskets. Over time they would fall apart and leave rubber remant all over the components.

I don't either... but just for a test it would be interesting as it would not cause the base to bow at all. I honestly think it doesnt make a difference one bit but I could be wrong.

you dont think what doesnt make a difference?

[nikhsub1]

I dont think that 'filling the gap' makes any difference with a stock fuzion. Nozzled maybe a different story.

[leo_bsb]

Looking at the last pictures I have another opinion.
Maybe that gap was intentionally projected to lock the nozzles. So the nozzles were mean to be locked by that gap, sealing it. What do you guys think?

Nice theory but I can assure you that is not the case.

Hey Martinm,
I can see your headed towards full testing of the Fuzion with your washer and nozzle in place. I have not had a chance to publish these results here in a more current Showdown at High Noon article yet (I just finished grad school and have spent the last two weeks moving a Penske truck across the country to California), but my results (with the gap filled) were slightly different:

Q6600 (at 3.2 GHz) with MicroRes/MCR 220/Fuzion/MCW60/MCP 655 and 1/2 inch tubing as follows:

Load (with the gap unfilled - stock) - 42.3 deg C with 1.83 gal/min flow
Load (with the gap filled - 0.5 mm washer) - 40.8 deg C with 1.93 gal/min flow
Load (with gap filled and custom nozzle) - 39.7 deg C with 1.48 gal/min flow

Hope this helps out Martinm,
Jay

Nice work, that does help alot! Thanks Jay!!

[Martinm210]

FYI
Went down to my local home improvement center and found this 1/16" (1.6mm) o-ring. Cost me $1.29 for two..



It does however bow the base, and actually after trying it, I wouldn't recommend anything thicker...seems like plenty of bow to me, here is the straightedge test after installing the 1/16" o-ring.

Jays results seem to say otherwise. Care to do some testing on your rig?

[nikhsub1]

No. I know that bowing like what martin is showing above definitely increases performance, 2-3c or so.

any pics of the washer? any specific type of washer?
