Slight mod to my Asus V Guard Series Cooler

[MUff1N]

As you all know the cooler I'm using is OK for default speeds and voltages, but when it comes to overclocking it has a harder time keeping the CPU as cool as the other more expensive models with more (or better) heatpipes & more surface area fins.
So this is what I did to it...
I added a 60mm 12v fan to the rear of the heatsink to where it's now got a push pull fan configuration.

There's an Aux fan header next to the NB that I plugged it into next to the cooler. (Left side of cooler on installed pic)
Works pretty good if you ask me...Yet another innovative idea working with what I got and doing the best I can with it!
Lowered the overall CPU temps by 20F.

Here's the diff after 3 days of the thermal paste setting in. Should get a bit better by the middle of next week.
I used OCCT 2.0.0a to do the stress testing. Download - OCCT Website english

Before
3.1Ghz = Too Hot @ 62c/144F (before cooler mod, 3 mins full load then heat warning and OCCT shutdown)
Gaming: 118-128F on Cores
Idle = 101F/38c

After
3.277Ghz = Better @ 54c/128F (after cooler mod, 15mins full load)
Gaming: 102-112F on Cores (112F is @ 75% CPU usage during gameplay)
Idle = 90F/32c

When I do finally do get a Good CPU cooler I'm going to use the 60mm fan on the Northbridge HS & see about 3.6Ghz...

Good job.
When I was OC'ing I modded my HSF in a similar manner-but what I had was a LG copper core cooler with a shroud. I didn't like the temps I was getting either. I removed the shroud and mounted another fan on the side. Worked well-like yours. Feels good to have an idea-implement it-and have it work.

As the ambient temps keep rising in my room so does the load temps.
But my idle temps are much lower and it cools down much quicker than it used to...
I still need a better cooler.
I'm now running at 3Ghz to keep the load temps within reason.

I like the way you said "--keep the temps within reason."
I recognized (for me) that whatever the numbers were, I had to feel comfortable with them. "Within reason" was the temp I felt good about. I could not go with whatever graph or temp table or Mg's recommended unless I felt good about whatever temp the CPU might be running at. If it wasn't, I'd just worry for a while and then do something to bring the temps "within reason."
I've never OC'ed this CPU, just ran it stock but with a large, copper core HSF. Never bothered to chk temps-no reason to. When by chance I did chk, it was running 125 deg /no load. That shocked me a bit. That temp didn't bother anyone else, and there probably is no reason that it should, but that was to high for me. I made some changes in cooling and now runs 105 no load to about 120/125 with load. Now I feel that is OK. It is now " within reason"
My 2 cents.

You pretty much nailed my thought on me being comfortable on temps.
It's not so much what the specs say it will run at, so much as what I'm comfortable with.
The specs say my processor will run up to 140F.
But what I'm comfortable with is up to 130F or less under load.
Same goes for my graphics card...

If I saw mine at 140F, I'd shut everything down & go into panic mode!

I've had it as high as 144F under full load clocked @ 3.46Ghz.
That made me a bit nervous, so it didn't stay there more than a few seconds...

Like I said, a lot of it is relative to how you feel. When I saw mine at 125F, I didn't like it. My case has a number of mods so I didn't have to do much. I had a 5 1/2 in fan on the side panel so I just pluged it in. Temps droped quickly, buy now I remember the problem with it. Noisy!
I just unplugged it. Plugged in a 3 1/2 case fan. CPU temp is back up to 120F. Doesn't seem to bad now-Compaired to the noise!

You are one of those that likes a very quiet computer.
I have 6 case fans going not including the PS and the 2 fans on my CPU cooler.
I'd rather have a bit of noise & a cool computer than quiet and hot.
Although I do use Speedfan to regulate the fan speeds so that when it's needed they kick up to full speed and when not needed they run at much slower quieter speeds.
So while gaming and the volume is up (LOL) I don't hear them making all that noise and while just posting on the forum they are quiet enough for me.
