Redid a loop, and temps worse! suggestions.

[Nostromo]

Old loop

HK 3 all copper MCP655 full speed Thermochill 120.3 with 3 yate loons.
Northbridge on own seperate loop.

New loop

DCC (older orange impeller) Feser 120.3 Apogee XT 3 scythe kaze 3000's
on fan controller. Northbridge on loop with cpu.

My idle temps are higher, and load much higher with new loop. Ive reseated apogee, used two different backplates, inlet and outlets are correct. Bled system. DCC rpm reads 4500-4900 rpm.

When the system was bleeding the bubbles were FLYING through the system , so it appeard to have excellent flow.

Is the apogee xt not as good as the hk 3? or is the older Dcc not pushing enough? any suggestions i can try?

EDIT: forgot to mention i changed collants also, from older MCT-40 to feser one.

Why not try Distilled water with Silver coils or PT nuke?
Still that would only be a few C at most.

Try taking pictures of the loop.
Post them up. Dont post just one picture, try to get a few angles in.

[antiacid]

so you put in a smaller pump and added a component to your loop and now you're surprised that the temps went up?

[Waterlogged]

Does the DDC have a top? If so, it's pushing more than enough.

I am curious as to why you switched to a block that is a bit long in the tooth from something newer?

How much higher are we talking here? Could ambient temps have played a part?

The dcc has a petras top on it.

I got the apogee XT thinking it was Supposed to outperform the HK by a few C, later found out it's about even with the Lt, but I thought it would at least match the HK tempwise.

Ambient was 64f in room. 920 D0 HT on 1.45V with my old loop I would hit 75-85c on load (prime) but with this loop i hit 90-100.

[Waterlogged]

Hm, I'm gonna have to echo Kurz's request for some pics. I have some suspicions but, I need to see if I should even bring them up first.

there are micro bubbles in the loop cause i re-introduced them to make sure i had flow. pump is off in these pics.

15C higher temps, I would be looking at mount/tim, especially if that is immediate load. I know you mounted twice, but XT base is bigger than HK, check and see if block is hitting anything like one of the caps preventing normal mount, see pic I drew red arrow on. Also, you did not use mx3 by any chance did you, few, including me got some bad/nonusable batches of it.

1. how is your xt oriented?
2. is the top properly aligned with the block internals?
3. how slow are you running your fans?

[Nostromo]

RGE- the base is very close to that cap, in fact, if i slip a piece of paper
between cap and base, it slips though and when i pull it out it's so
close it almost feels like it being grabbed.

I used ceramique, AS5, and a tube of something that came with a block
it's gray with a blue cap.

Warriorpoet- it's mounted with 3 bolts toward lockdown lever like directions
state. 2 sides have 3 bolts, i mounted it exactly as pic showed
with outlet barb closest to cpu hold down latch pivot point.

internals of the block lined with top?, wow, not sure on that one
i did not take block apart so i assumed it's correct, but you
never know. I have two of these blocks too and did not compare

fans full speed even had 6 in push pull, did not matter.

[Vinas]

Maybe consider checking the block. I had some gunk in my XT and no idea how it got there. It was like blackish jelly stuff. I used a toothbrush and dish soap with hot water to clean it out.

I would expect about the same performance from the HK3 vs the XT. There were some reviews that really recommend the block but IMHO performance is about the same. For instance one guy reported these scores (http://www.overclock.net/water-cooling/590728-my-apogee-xt-extreme-vs-heatkiller.html) in a one to one swap out of blocks:

Apogee XT Idle: 32 29 31 28
Heatkiller 3.0 Idle: 35 32 33 31

Apogee XT Load: 58 56 56 55
Heatkiller 3.0 Load: 60 59 57 57


So in that case your block should act pretty close the same. I noticed in one of the pictures there appears to be some foam over the front of the rad... Is this just an optical illusion? Did you switch out the PA120.3 for the Feser? I think the PA out performs the feser for the most part...

[Armitage]

This may sound like a pain in the ass, but try setting up your old loop. And see if you can replicate those temps again.

[Nostromo]

Vinas-The 'foam' is actually a filter material I cut out to cover the whole rad, I have removed it. and made MAYBE 1C difference.
I switched the PA with a feser because I was trying to get 3 builds going, and for this one I just grabbed the feser i could kick
myself now, cause i got two fesers, and they had TC's in stock, shoulda just got those, but thought try something new.
thanks for the temp numbers on the block, the blocks should be fairly equal within a few 'c' which makes no sense to me.

Which brings me to..

Armitage-I think that is going to be my next step, the HK is on a different build I am not tearing apart right now. so I think I am going
to order another HK and rebuild the loop like it was.

Or should i try the new EK Supreme? Hmmm. but it looks like it has a large base too.

thanks guys.

[Vinas]

I've heard good things about the EK supreme HF... Maybe worth a look?

[Nostromo]

Well after i thought about it a bit i realized i should hold off on new purchases for a bit. so i decided to remove the NB from the loop.
I took the hoses off the XT and looked into the inlet and saw some black stuff. took the block apart, and sure enough like vinas I had
'some' black stuff between the pins and a PILE of it right at bottom of inlet, so not sure if it was from block, or if the xt 'filter' caught
other stuff from my loop

so this is gonna be CPU only loop for now, NB HS is on, bleeding air now.
