TRUE Results

post #1 of 14
Thread Starter 
So I upgraded from an Arctic Freezer 7 Pro to a TRUE this week. Idle temperatures for Arctic Freezer 7 pro were around 39-42C and load reached 70C.

First off, I'm going to have to say that I totally screwed up lapping my TRUE AND seating it. I only bought 1/4 sheets of sand paper for each grit (400-2500) and it wasn't enough to lap both my cpu and TRUE. Also, the 400 grit wasn't enough, so basically it took me 5 hours to try to lap this thing as best as I could... I didn't know that the 1/4 sheet of 400grit would lose its roughness that fast! I wasn't even able to get all the nickel off.

I put a very small amount of MX-2 thermalpaste on. Then, when I seated the TRUE it was all crooked. So then I mistakenly lifted it off the cpu to try to reseat....then I notice that I lost the contact between cpu->thermal paste->TRUE. I was too lazy to repaste(after 5 hrs of lapping).

I knew I wasn't going to get as impressive results because of my laziness. Idle temperatures were unchanged from the Arctic Freezer 7 Pro. Load temperatures saw a drastic change: highest temperature is 57C! For a half-ass lap job and seating, I'd say thats pretty good. There's also something interesting...my lowest core temperature is 47C! Thats a 10C difference...somethings wrong. I probably screwed up the lapping.


I plan to relap within the next week. Hope I get good results!

One question: How are you suppose to install the backplate? In the instructions it just says to place it back there... Do you have to remove that plastic X thingy? Or remove the black square?

Sorry for wall of text, I'll get pictures in for relapping!

You don't have to remove the square on the backplate, just get double sided tape so its not stuck on the back of the motherboard so if you have to RMA the board.. Also what fan are you using? If you use a 120x38 fan you'll see a slight difference.

Pretty good results for your....work!

Get some 200 grit to quickly get it flat again, then along with a 120mmx38mm fan you should see about 5C lower load, maybe more if you lap job was THAT bad lol.

You might have to lap your cpu. I have a TRUE as well in another one of my computers, and actually had a 20 degree difference in temeratures in cores under load... I lapped the true, and still had the problem. It wasn't until I had lapped both the true and cpu that the problem vanished. My cpu was VERY concave.

There will still be a variance in core temperatures, just not that drastic. Once I fixed the problem 2 of my cores were the same temperature, and the other 2 were within 2 degrees of the others under full load, and I was thrilled.

No leave the plastic piece, prevents metal to metal contact with the mobo.

They don't specifically mention anything about the backplate other than mounting it in the Ultra 120 Extreme installation guide. However if you take a look at their XWB-1 water block installation guide (using the same backplate), you can see they specifically mention NOT to remove the plastic piece. Hence why people who DO remove it usually have issues getting the backplate off the motherboard, cause it's become glued on.

Awesome!...Now I hope I don't have to unplug and take everything out. Well, just waiting to get sanding paper. Also have to visit Home Depot for 200grit sanding paper. And I need to find a washer!!!
