I decided to rebuild my system to make it quieter and cooler. Since it is a two-year-old PC (running Intel® Core i7-860), I didn't want to spend too much, as I will, likely, want to upgrade to the next generation CPU next year.

I replaced my case fans (Antec 300 stock fans) with Nexus D12SL-12BL 120mm fans. I did a bit of cable management to improve airflow, etc. I first bought the Cooler Master Hyper TX3, but found the 1156 mounting pins extremely flimsy, and the cooling performance sub-par. I am going to use it for my AMD-based file server. I searched for an alternative, inexpensive cooler, and decided to buy the Thermaltake Silent 1156 cooler. What a nice surprise this turned out to be! Everything was significantly better than the TX3: the packaging, the fan, even the fan cord. The mounting pins were sturdy and extremely easy to use. I applied the supplied thermal compound and mounted the fan without much effort. The fan takes up surprisingly little room in my case; it does not interfere with any other components.

I am using an Intel P55 board, which has a really nice temperature and fan management system, controlled in the BIOS or via free Intel software. Even at heavy load, the cooler remains cool and quiet. I ran my tests on a hot day (80F) and my CPU temperature at idle was around 35C, and peaking at 65C at full load (running Prime 95 CPU stress test). This is a significant improvement over the stock fan. I must point out that I run my CPU at stock speed (2.8 GHz), and do not overclock any of my system components. I have an EVGA GTX460 video card.

My case is set up with four fans: two front intake fans, one top and one rear exhaust fans. If your Thermaltake Silent 1156 fan is loud, chances are, the fan is running at a really high RPM.

Great cooler. Very easy to install. Dropped my temps considerably compared to stock cooler for my intel 2500k. Average idle temps are now 40c, when compared to about 50c with the stock cooler. Also, this cooler is extremely quiet. The best thing is that the heatsink is slanted and its footprint does not go outside the holes in your board for the heatsink. This way it won't get in the way of your memory if you are using all your memory slots. The heatsink size is just right and will fit in almost all cases.

Purchased the Thermaltake Silent 1156 after doing an RMA for a Zalman 92mm CPU cooler that did not fit on a ASUS P8P67 Deluxe motherboard due to the blue heat sink fins on the board that surround the CPU. This cooler fit within the blue cooling fins surrounding the CPU socket and snapped in very easily on top of the i7 CPU. Most of all, it is very quite compared to other CPU fans I've used in the past. The build also uses a Thermaltake V9 aluminum case and 575W ToughPower PSU.

To be honest, I did not know what to expect. Most reviews gave a positive response but some said it was a bad or mediocre cooler. Well after putting in my first cooler I am amazed at the results. Dropped my core temps 10-15 degrees. I am not an overclocker so I am very pleased with the performance and it is just as advertized very silent. I don't understand how some had problems with the clips...they worked perfectly...it did take a few minutes of messing with them to find out you push in and spin to lock them but it was more than adequate to hold the cooler.
I am very happy and will probably order another one for my sons desktop because of the silent operation and the impressive performance. For 20+ bucks you can't go wrong with this cooler. Also, I have a standard to small ATX box and close to 2 inches of space so it will fit standard cases w/o any probs...
Again, this was my first purchase of a cooler and install...can't say anything about the thermal paste because it hasn't even been a week since install...i will update later...it is ok with temps now but A.Silver would probably only give better performance.

This is cooling an Intel Core i7. I switched out the fan that came with the processor and it dropped core temps by about 30 degrees Centigrade. It is very well priced for what it does. I've had it running 24x7 in a server under load for 3 months and it's still working great. Due to its vertical orientation it contributes to the "in the front, out the back" air movement for the whole case (if you face it the right way). It's a nice benefit I hadn't considered.

Installation was easy and now my CPU runs about 10 degrees cooler than it did with the stock i5 fan. It is running on slow (900 RPM) and is barely audible and very easy to tune out. When it runs full speed it is noticeable but not bad at all. I have yet to have it ramp up on me during normal use, though.

I found this mid-sized cooler to be perfectly effective for my i7-3770K setup. I'm not sure if the angled design of the fan helps or hurts it, though. At low speeds, it's reasonably quiet, but there is a persistent low-frequency hum that can't be eliminated as long as the fan is spinning. Fortunately, this hum is quiet and may not be audible (or only barely audible) if the PC is under a desk or such. At higher speeds, it makes some noise -- not a lot, but not just a little; but also does a relatively good job at cooling. It's okay for overclocking, just nothing too heavy or dramatic.

Installing is easy, at least on the standard Intel lines. Just secure the mounts to the baseplate with two screws apiece, apply the thermal grease, line it up and move it around a little bit to spread out the grease, line it back up and press the mount pins until each one locks into the motherboard.
