Is this the best cooler money can buy? Of course not, it's $20.
But is this probably the best value cooler w/o spending $50+? I'd be hard pressed to find a better one.
My basic setup: AMD Athlon II X4 630 (2.8 Ghz mild overclock for now to 3.2 Ghz), MSI mb, 2 GB DDR2 ram, XFX ATI 5750.
With the stock heatsink and fan at this O/C my idle temp was ~ 32-34 C, at load around 52-54 C.
Not a difficult install, instructions are terrible but for an AM2+, AM3 chip it's quite easy with no tools, and do NOT have to remove the motherboard from the case (can not speak for Intel chips), just takes a little common sense although the thermal grease supplied is pretty bad (like rubber cement).
Anyways after the TX3 was in place my idle temps are now at 22-24 C and at load 36-38 C. I'd say for a $20 cooler that isn't too loud, that's a pretty good result. Cooler Master RR-910-HTX3-G1 130-Watt 92mm Hyper TX3 CPU Cooler for 775/1156/AMD/AM2/AM3
I am overall greatly impressed with this HSF for its price to performance ratio and ease of installation.
I purchased this CPU cooler for a new Socket 1156 (Core i5 750) build, after having already built the computer and using it, the stock Intel HSF was a great disappointment. Intel's stock HSF is about half the height of its usual circular fin array. It also performed, in my opinion, horribly. At idle the temperature was around 38 degrees Celsius with the fan being audible over other fans and components. At full load it approached 76 degrees Celsius, which was disturbing enough for me to not perform a prolonged stress test on the CPU. The fan at this point was a very audible whirling, like most small fans running at high RPM pushing air over a small surface.
This HSF was an easy installation, no need to remove any components. It uses the standard push-pins for Socket 1156 compatibility. With its light weight and compact size, I am confident the push-pin locking mechanism will be adequate for holding it in place. I used OCZ Freeze thermal compound, for its ease of use and no need for a burn in period. I ran into a little trouble when attaching the fan, the metal fasteners need to be oriented correctly for their middle section to lock into the grooves of the heatsink. It takes a little coercing of the tension. I had to be careful of the fins, as they are not completely dull. I managed to snap them in place without hurting my fingers.
With the installation complete, I proceeded to the testing phase of the setup. Because the fan uses a four-pin PWM connector, you will have to rely on the BIOS settings to automatically or manually control its RPM. In my case my board needs to use an OS utility for advanced control, I am using Windows XP, so it took a little time to get oriented to its behavior.
I was immediately pleased with the idle temp staying at 23 degrees Celsius. I monitored it while it was idle for about an hour observing no change. That is an improvement of 15 degrees Celsius over the Intel stock HSF. The fan during this idle period tended to stay near 1500RPM. When I was manually adjusting the RPM, I found that 1500RPM was just under the range where I could here the familiar whirling. So I locked the idle temp to 1500RPM. Under full load I was again pleasantly surprised to find that the fixed 1500RPM kept the temperature from going above 56 degrees Celsius. That is an improvement of possibly more than 20 degrees Celsius over the Intel stock HSF. The next greatest benefit is that the noise the fan makes at 1500RPM blends directly into the ambient noise of the other system fans.
My system build is as follows:
Antec Mini P180 Case
Gigabyte GA-P55M-UD2 micro-ATX
Intel Core i5 750 (stock settings)
G.Skill DD3-1333 2048MBx2 CL 7-7-7-21 1.5v
I've recently built an AMD Athlon II 425-based computer (a certain regional electronics retailer well-known for their CPU/motherboard combos made an offer I could not refuse. What I paid for the CPU works out to less than forty dollars.) Naturally, and like most other people who choose to assemble their own PCs, I could not resist the allure of overclocking. Of course, stock cooling solutions are adequate for... well, cooling the CPU at stock settings. Since all modern CPUs have great overclocking potential but get quite hot when doing so, I wanted to upgrade my cooler.
After some searching, I found the Cooler Master Hyper TX3. In keeping with the philosophy of my build (buy the product at the point where performance just about stops increasing linearly with the price), I made the purchase, and the product arrived at my doorstep a few days later.
Cooler Master has elected to use plastic blister packaging for the Hyper TX3. It was easy to open, and required no scissors, which is a refreshing change from most packaging of this type. I received the universal version of the cooler, meaning my version of the TX3 supports Core 2 as well as Core i5, along with pretty much all Athlon 64s and above (Athlon 64, Athlon 64 X2, Athlon II, Phenom, Phenom II.) The cooler does not require installation of a motherboard backplate for use. Since this is a smaller cooler, it uses Intel's standard push-pins or AMD's clips to remain secure. Cooler Master has apparently revised the TX3 recently; previous versions used a clip to secure the 92 mm fan to the heatsink. This clip received VERY mixed reviews (Yes, I do mean VERY - some reviews were absolutely glowing while others had the deepest contempt I have ever seen. Okay, maybe the reviews were not that extreme, but I did see a lot of love and a lot of hate.) The new fan retention mechanism is made of plastic. The fan is secured to the plastic mount with screws, and the mount itself snaps onto the cooler. Rubber pads are used to dampen fan vibrations. Also, this revision apparently makes the gap in between the heatpipes and aluminum smaller, which is always a welcome change.
The TX3 comes with one 92 mm fan, but comes with all the necessary accessories required for attaching a second 92 mm fan for a push-pull configuration. Cooler Master also included a tube of thermal paste, which is a nice touch, though I elected to use Arctic Silver 5 instead. I did search online to see how good Cooler Master paste is, and although it is not as good as AS5, it does easily beat the thermal pads that come default with many heatsinks.
Now, as for installation... I can only comment on AMD. Installing the TX3 was not as easy as the stock heatsink, as the TX3 is larger, leaving less room for your hands to maneuver. Additionally, I chose to go with a micro ATX case and motherboard, leaving me even less room. Whereas the push-pins for Intel are attached solidly to the heatsink by screws, the clips for installation into AMD-based systems are only secured when you finish installing the heatsink. Before installation, the clips are kept in place mostly by gravity. They're also two pieces, so when you're fumbling around in a small space trying to install the TX3, you might bump a clip off the heatsink.
This cooler is about 140 mm tall, according to my measurements, so it'll fit into any standard ATX-width case with millimeters to spare.
I've seen some comments (complaints?) about the TX3 using a 92 mm fan as opposed to a 120 mm fan. For a cooler in this price range, I am not sure if those complaints are valid. Remember, the stock AMD fan uses a 60 mm fan and spins at over 3000 RPM. I'm going to guess Intel uses something very similar. This cooler is 92 mm and spins at 2800 RPM maximum. Beats stock, yeah?
As for the part everyone cares about. Performance beats stock, of course. Keep in mind I am using a micro ATX case. Also, I'm providing CPU temperatures, not core temperatures. The diodes used for monitoring core temperatures are not accurate at lower temperatures. They're built into the CPU for throttling (they save your CPU from becoming an expensive key chain holder.) Idle temp stock is 38 to 40 degrees Celsius, depending on time of day. TX3 is able to do 32 to 35 degrees Celsius. Full burn from Prime95, stock reaches 71 degrees Celsius, while the TX3 keeps it under 53. I've since overclocked my CPU from 2.7 GHz to 3.41 GHz. Max temp I've seen in Prime95 is now 58. Not bad for $20. Your results will vary depending on what thermal paste you use, how well you've installed the cooler, whether or not you overclock and how much you overclock, how well air flows in your case, what else you have in your case (buff graphics card? =) and so on.
Well, I'm happy. Great cooler. You can buy this and be unhappy at the small stuff like how the part of the heatsink that makes contact with the CPU isn't perfectly flat, but you have to remember this is a budget cooler, and also a perfectly flat heatsink is just a means to an end. You buy a heatsink because it cools better than stock, not because it has a perfectly flat surface. A perfectly flat surface might cool better, but then again, how much better? Remember, this cooler has direct contact heatpipes, so there is going to be some gaps. The heatpipes and the aluminum also have different coefficients of thermal expansion, so maybe the surface does get more flat when it's in use ;p. Also, does a "nonsmooth" direct contact cooler beat a mirror-finish non-direct-contact cooler? Think about it! - Amd - Computer Heatsinks - Cpu - Cooling'
