Degraded Venomous-X Temps

post #1 of 7
Thread Starter 
I started with the Ven-X with the same fan config (2x ap-15's) about a year ago when I was only clocked at 3.8ghz @ 1.28v on this Q9550... I was getting stuck sensors ~ 33-37C on my idle temps, but load would go no higher than 55-57C with Prime 95 Large FFTs...

then i went to a p45 board and 4.0Ghz at 1.31V... IIRC load temps were ~ 58-62C w/ prime95 Large ffts...

Now... 6-8 months later at the same volts/clock, I get 62-64 on Blended, 65+ on Large FFT and IBT takes me to almost 80C.. (which i only allow to run for a few minutes tops..)

I have a PC-9F w/ all ap-15s around (just took out my xigmateks) plenty of air coming into the front w/ dual fans... 2ap-15s on the ven-x and another ap-15 right behind it inline exhausting the cpu area... Still have a 140mm xigmatek running @ 900 rpm venting upwards too... ambients are ~ 22C..

I heard a while back people were saying Ven-X coolers can mess up sockets and cause increased temps... I did run it at full pressure for 2 months when I first got it, but decreased it to ~ 50% afterwards and have had no issues with my PC/CPU/Socket acting up.

I have tried as5, mx-3, tx-3, etc. etc. lines, dots, double lines, razor spreading....

I even lapped the ven-x 2 days ago which only got me ~ 2-3C in better temps...

Anyone have any clue? i feel like my great load temps are gone for good with this build =(

I might try to mount my old lapped tuniq 120 tower to see if its the heatsink or not...

I don't think its your HSF, I think its your CPU degrading after being overclocked for so long. For me I always find how high my clocks can get on stock voltage and leave it that way for 24/7 use. I only overvolt for benchmarks.

Retarded question that I'm sure you've done but didn't mention; you have cleaned the dust out from between the fins, right?

I am well within the Intel limit of 1.3625v, plus it has never been unstable or asking for more voltage? I thought degradation was mainly a stability concern not a heat concern.

LOL good follow up, but yes, I blow out my case and heatsinks ~ once a month with a compressor in my garage.

UPDATE:

Found my rear pull fan was not quite running full rpm for starters,

then I pulled the ven-x off again to check the pattern of the TIM... very flat in the middle and thick on the edges... re-did my lap job to make it flatter and i think i nailed it this time.

Applied some fresh mx-3 in vertical double lines (suggested for intel 775 quads) and voila... 51-52C max on prime blended the rest is similar.

Use middle blob for TIM. Best method. Tried and true.
