O'C my i7 920 processor, but temperature is pretty high

Diabolical · 26 Oct 2011

well i dusted off my Desktop and the temperature dropped about 10C on each Core, its about 49-55C overclocked at 3.2 ghz.. for the heatstink i would have no idea how to do that, i really had never performed any operations inside of my desktop.. is there any test that you can do to test if the watercooling is really working?

P.S i found out that the liquid cooling got is Asetek liquid cooling, if any of you know any information on this type of cooling system

I'm pretty certain that is a sealed system liquid cooling setup, meaning that there is no user maintenance required (or even possible). Does it look similar to the picture attached at the bottom?

What you can do is replace the thermal paste between the cooler and the CPU. Since you've mentioned that you're not a computer expert it would not be a bad idea to get a more experienced person to help you do it. It's not hard at all but there are a few little tricks to getting it right - and a few places where a mistake could be costly.

This video might give you an idea:

eh.. this looks kinda scary, and i do not know any computer experts other then my uncle, but he lives far from where i do (out of state), you think a computer repair shop will solve this?

A shop would be glad to do it, but they might charge you an arm and a leg. If your temps fell 10C just from a fan cleaning I might be inclined to tell you to wait on the thermal paste. if you're not comfortable with the idea, you would be better off watching someone else do it before you try it yourself. Also, I would not remove the CPU from the socket like he shows in the video. That's just one more place for a beginner to go wrong.

Looking back at the bottom picture from my previous post, see the part on the left? If your cooler looks like that then that part is the radiator. Make sure it is dust-free and has good air circulation through it. The part on the right that says "asetek" is the cooler on the CPU. The coolant flows up one of the tubes where the heat is removed by the fan(s) blowing over the radiator, then the cooled fluid flows back down the other tube to cool the CPU. Keeping that radiator nice and clean makes it easier for it to dump the heat out of the back of your case. :)

The best way that I have done is to remove the fans from the case every 3 to 6 months. Then take the removed fans to a well lit area, such as a desk, and clean them by hand. In my case I see about a 2-3 C drop in temps at most but it makes the fans last longer and I know I can leave my system running when I am not home and do not have to worry about something bad happening.

As for the radiator I put mine in a plastic bag which is doubled baged (all while still attached to the CPU) and use a can of compressed air to blow out the dust that sits in the inlets for the air flow. I only have the nosel of the can inside and the bag is closed. You hold the radiator towards the top of the bag and push the dust to the bottom. Not 100% at getting all of the dust but it gets most of it.

Diabolical,
I would invest in several cans of compressed air or if you have access to a compressor like many people have in there garages with a reservoir tank on it then purchase or locate a high pressure nozzle. I don't like to clean with air inside the house so disconnect and take to a safe outdoor location. I use a soft paint brush, an old tooth brush, Q tips and air. Use the brushes first to get most of the dust then spray the fins of the radiator, mobo and fan blades. Look to see if your system has hidden front air intake fans, fans underneath and access and clean them all. This deep cleaning needs to be done once a year minimum and every quarter is best of more often if you have carpet and pets. When using the nozzle please use light blasts and remember there are delicate things in the computer so pin point the dust and dirt only and back away for mobo and overall dusting. Some say that we should hold the fan blades as they can become little generators when spinning so hold the blades stopped with your other hand. Concentrate on the radiator as I'm sure it still has lots of dust in it! Good luck and report back.

ok well, i finish playing some of battlefield 3 at High Graphics, it lagged and spiked a bit, but for the most part it ran pretty smooth, I tried Ultra high graphics but i experience extreme lagg, this game is intense, ull need to O'C your processor to 4.2-4.5 GHZ in order to play at Ultra High graphics.. But besides the point, my average temperature was about 72C-76C while playing, is that normal?

Dude. That doesn't seem right. Battlefield 3 does not use much processor at all. It runs as fast on an i3 as it does on a new Bulldozer (see the end of this article). Overclocking is not going to help that. I have a single 6970 and I play BF3 on Ultra flawlessly. You should be getting be getting somewhere around 100 fps with your graphics cards. Seriously. That said, I know there are some bugs with crossfire and bf3, update your drivers to 11.10 R3 and CAP 4, that will get you the best results.

And regarding the temperatures. No. That is not normal. That would be normal with a stock air cooler - either there is something wrong with your water cooling, or it is not mounted well with good thermal compound.

But again, update the video card drivers, that will make a huge difference for BF3

Is the overclocking completely necessary? I'm sure I could run at stock speeds and get somewhat of a good result.

#1 Rule. How Stable is this OC? did it pass a 24hr Prime95 run?
#2 What Voltage is the Vcore at?

There is a lot to over clocking, and a lot that will hinder results.
BTW AlienWare ain't anything to be proud of. i look at AlienWare the same i would a PC Pre-Built from a PC Store/Shop. Dell ect lol

this is more of a Guide than Copy my Settings!

My i7 920 @ 3.8Ghz for the last year and a half.
Room Temp was i think 23C & i use a H50 P/P.

might give you a idea of Temps and Vcore ect.
