CM 120mm Blue LED fan = 90cfm
Xigmatek 120mm XLF LED fan = 61cfm
(cfm = cubic feet per minute, higher the better)
- get another 120mm fan and Tuniq TX-2
- mod the casing to accommodate the additional fan (current casing only allow 2 max)
- improve casing air flow
- further modding if got time and cash
====================================================================
I start my PC operation after my dinner. As usual, I opened up a table as my operation table and prepare the tools and hardware that I will use in this operation. My brother decides to join in as well as he is eyeing on my new thermal paste. Anyway, it is time to clean the HSF of the old PC and reapply the thermal paste.
My brother will conduct his "operation" for the old PC under my guidance, while I will perform my own "operation" for my PC. We prepared the platform and simple tools needed.
====================================================================
TOOLS
- brush
- screwdrivers
- tissue paper
- cotton bud
- some sponge/foam
- scissors
- torchlight
- dry cloth
- receipt stand
- cable tie
- bamboo stick a.k.a satay stick
As you can see from the picture, there's thin layer of dust even after just a week of use. Looks like the filters in the front panel is not enough to filter off all the dust. Such amount of dust is acceptable due to the dusty environment my PC is placed now. And the filters did a good job of blocking most of the dust entering. After half a year of operating and the hardware is still as clean as new (except for the graphic card which is harder to clean, but still consider clean).
After that, I remove the CM stock fan at the rear of the casing because it's blocking my way to dismantle the push pins. The pushpins are easy to detach, a screwdriver will do the job. Pull up the cooler with a little force and as I suspected earlier, I applied too much thermal paste last time when I install the RS. This can be determined by observing the excess thermal paste around the processor esp on the cooler's copper base.
Carefully I used the cotton bud to wipe off the excess thermal paste at the side of the processor and cleaned the remaining with tissue paper. I'm not too particular to clean it with thermal paste remover because I do not have any of it. So I will just let it be and read up and see if there's any side effects of not using it.
Using tissue paper and cotton buds itself is not enough to remove the thermal paste completely, so I took out the processor to clean it thoroughly. This is the first time I remove my E7400 from its socket.
After cleaning the processor, I placed it back to the socket and secure it before proceeding to other task. The next thing to do is remove the front casing fan to reallocate the location for each fan. This time my planning is to used the CM 90cfm fan as the main intake at the bottom, the xigmatek black fan as the rear exhaust. While the CM stock fan will be used as an additional intake fan at the top part. To do this, I will have to do some minor modifications to make space for the fan. Before this, the stock fan was used as exhaust and the xigmatek fan was used as the main intake. The diagram below will explain everything.
My planning is to open up the metal plates of the ROM bays to allow air flow and attach the fan there. What I had in mind is to cut a curved opening at the first and last plate and remove the plate in the middle. But unfortunately, I do not have the proper tools to do so, so I just remove the middle plate temporarily and see how it goes before doing further modding.Using a pair of scissors, I asked my sis to help me cut 8 pieces of coin shaped foam. 4 pieces for each fan, I have 2 fans that need to be screw. Using a receipt stand to make holes in the middle of the foam, I then screw the fan together with the foam onto the casing. From the picture below you can see that the foam is placed at the screw holes and act as a vibration-insulator between the casing and the fan itself.

Looking the base of the cooler, it is not actually smooth in my opinion. I'm so tempted to lap it but just don't have the proper knowledge and sand paper now. I will do so if I think I wanna squeeze more performance out of this RS.
Applying Tuniq TX-2 on my HIS IceQ4 4850 TurboX
My graphic card itself has a decent cooler installed, which is the IceQ4 version of graphic cooler. My model: HIS ATI IceQ 4 4850 TurboX, is one of the fastest 4850 at its time. With the newer graphic cards now replacing this, the price has gone down pretty much compare to last time. First, I unscrew 3 big screws at the back of the PCB. Then switching to a smaller screwdriver, I unscrew the remaining 4 screws which are on the back plate of the chip set. Carefully not to bend the back plate and lost the small screws with springs, I placed the back plate aside and continue dismantling the cooler.
Connect and double check all the power cables. I'm ready to give it a test run. Before that, let me summarize on what I've done today for the reinforcement project.
- Applied Tuniq TX-2 on E7400
- Applied Tuniq TX-2 on HIS 4850
- Add another casing fan i.e. CM 120mm 90cfm Blue LED fan
- Relocate the fan location to allow maximum air flow
- Simple modding at the 5" bay to accommodate a 120mm CM stock fan
Obviously I have a stronger air flow now compare to last time, but this also means more dust. I must clean my filter once every month at least to keep the internal dust free. Cleaning the filter is much easier and safer than cleaning the hardware.Giving a test run after everything shows that my rig is no longer as silent as before due to the 90cfm fan as the main intake. The anti-vibration foams are working great, no vibration sound were detected. However, the noise came from the friction of air with the holes. The fan itself is silent, but when the air passes through the casing holes, friction between the air and the metal creates noise, similar to vacuum cleaner, but not as loud. This is the sacrifice I had to bare in order to have good air flow. Basically the sound is only noticable during late quiet nights.
OK, as for the results.

So what happen to my old rig which has a E6420 on it? Well, Basically we did not clean the HSF for more than 2 years. We decided to give it a clean since we are going to change the thermal paste of it as well. After taking the dusty Intel stock HSF out of the E6420, to our surprise, it's a copper based HSF.
Removing the fan, we can see that the copper base is actually in a cup-shaped copper with aluminium fins around in. Inside the "cup", we found a lot of dust sticking on it. After some simple cleaning, the heat sink looks like this.
After a test run, the temperature of this hot E6420 drop tremendously to an idle of onli 32-33°C in cold weather!! But the temperature soon rose after the processor is stressed and the stock HSF cannot sustain the heat produced by the processor. On idle, the stock cooler is almost on par with the aftermarket coolers, the only thing limiting will be the surrounding temperature or the ambient temperature. If the ambient temperature can go lower, an aftermarket cooler will definitely leave the stock cooler behind. On load, the aftermarket cooler will pawn stock cooler with no sweat.
