Lapping on blocks

[kronchev]

I had this setup:

Dangerden Maze4
Hydor L20
Whatever the single heatercore they sell on DD is


I got about 10C over ambient, full load. 2.3 ghz, 1.7 volts

Now I have:

Dtek spir@l
Danner Mag 3
Big doublecore Bonneville heatercore

I get about 12-14C over ambient


My theory for this discrepency is I suck at trying to lap. Im pretty sure I didnt do a good job at the spir@l at all. My temps SHOULD be lower, right? At least the SAME, certainly not higher, as they are. Is it worth it to get one of the $6 lapping kits, drain my system, relap the block, and put it all back together? I just really dont like mounting the block...always feels like I'm gonna break something, either when screwing it down or when putting on the hoses (the spri@l has real bastards of barbs).

Thanks in advance

I dont think you should worry about 2-4C, and the spiral isnt known for extreme performance. I also dont konw what kind of air you are pushing through the bigger heatercore.

You can tighten a block pretty tight against the core, Dont let it go loose, especiall if you are putting thick tubing on it. One of the worst things you can do temp wise is put a lot of torque on the waterblock and allowing it to get crooked on the core. Not to mention the risk of cracking it.

2 evercool fans at 7v pulling through the core.

i know, i tightened it around 80%, looked at the board from the side, and noticed it looked like a ) so I loostened it to 60% (since the ONLY thing resembling instructions I could find was a review, and they said that 60% is the best tightness) the percents are for spring compression, btw.

i notice i didnt have this problem wtih the maze4. I tightened it all the way and it bent the nylon supports to all hell but it was completly tight and the board didnt warp as much.

so do you think that if I lap it fully and carefully, then do what I wanted to do originally, which was open it up and take a drill press and put a lot of dimples all over the inside channel, itll be better? i know someone with a TC4 and the normal heatercore, i dont know the pump but it wasnt anything spectacular, he was getting 3 or 4 F above the ambient by dimpling and lapping. the spri@l is supposidly better and, well, its what I have

OK, i ordered the standard lapping kit and some AS5 from easypckits.com. I have been playing around with my fan speeds and have discovered my temps do not change AT ALL if my fans go from 7v to 12v, so in the interest of sound, i'm putting them back to 7. I could even try 5 I suppose, but the molex->3pin adapters I'm using arent very happy as it is with the switching ive been doing

hey look at that...

I dumped a bunch more waterwetter in and my temps are now 8C above ambient, prime95ing...thats a 6 degree lowering

im now concerned theres air bubbles in my core and possibly in the proc...gotta rotate sometime. unfortunatly the pump isnt secured so it wont be easy, plus, you know, im using it
