i7 950 High Temps W/C Pump Failure

post #1 of 9
Thread Starter 
I had an Intel i7 950 at stock settings under a water cooling loop.

The loop has never been real "cool" no matter what config it has been in be it CPU only GPU's included etc... but the other day i noticed the waterpump was no longer pumping and well we all no what happens..

My CPU i worry is screwed. The temps were all pegged at 100 Degrees Celcius. I don't know how long this went on but i assume many hours. I don't understand why the pc just didn't shut down.. argh..

anyways.. I have removed the loop and have the stock Intel HeatSink/Fan and idle temps are in the mid to high 50's . I ran prime95 and instantly temps went to 82. I stop this.. I am in the middle of resetting HS and reapply AS5 as that is all i have atm.

Ambient is approx 25.2 degrees celcius

Ideas? Is this processor "cooked" for a lack of a better word.

In CPU-Z the core voltage is not showing... i believe it has in the past.

guys... please.

I have done some more reading and it seems that the stock cooler is crap and my temps are close to correct.. Idle is a little high.. I have ordered an H100

Hi,

Should have throttled a little over 90c and if didn't, for extended period
could be looking at cpu problems.

Default (All) your settings and start from scratch with updated cooling.

If high temps at idle and load at default settings could be looking at thermal damage as to the CPU.

All I can think of.
Good Luck.

ZP,

What kind of WC setup were you running?

Regardless, your i7 will start throttling down its speed at 100C; even at that temperature though, you could run a stress test without any errors. Ideally, you want to keep temps under 80C...for not only a little headroom, but maximum life, efficiency, and performance.

If you haven't already, go ahead and reset everything in your BIOS to defaults.

A couple of quick questions (as I don't want to assume anything):

1. Are you sure that the HSF is being attached properly?
2. Are you properly applying AS5?

Look forward to hearing back.

The first thing i did was reset BIOS to defaults and also update the bios to newest and then reset to defaults. The only thing i changed in the bios was to use the RAID and the XMP profile for my memory.

I had 2 different setups..

Dual 360 rads cooling CPU and 2 470 GTX's

Latest was just a single 360 rad cooling the cpu w/ an EK Supreme HF block and an Black Ice RAD w/ DDC-3.25TPMP pump on XSPC Dual Bay Resi.

I have applied AS5 multiple times using grain method, pea method and the results are all the same. Obviously cleaning everything with 91% Isopropyl Alcholol prior to new applications.

I have ordered an Corsair H100 just to keep things simple this time around. Don't know why my pump stoped working .. it was only a year old.

Hi,

I lost a 355 pump after 8 months but caught it in time.

Mine was intermitant, sometimes yes, sometimes no
Gabe replaced it.

Reason have res where I can clearly see it thru side panel plexi.

For future builds, install Coretemp and enable the security feature. If my temps ever hit 80C, it shuts down my computer. Great piece of mind.

Hi,

Good idea

When rigs on pretty much not left for any lenght of time,
But doesn't take long!
Especially with three rads and alot of connections.

Never on overnight so helps that way.
