Help with heat sink?

I'm using an i5 3570k processor at stock speeds with the stock heat-sink that came with it, been using it for about 6 months now and I've been getting temperatures of 80-101 degrees today playing Guild Wars 2, and it's been drastically slowing down my performance as well.

I'm looking to buy an easy to install heat sink that'll work for my CPU, I don't really plan on overclocking, I don't know how and it seems to be fine @ stock speeds for the game I play.

The stock heat-sink that came with my CPU is really easy to install and i'd like something similar, just latch 4 points onto the board and i'm done.

Anything $50 or under is fine with me, i'm just clueless on where to start, any help would be appreciated! :)

  1. Firstly, try cleaning the dust out of it and checking that the rear case fan is an exhaust and the front (if present) is an intake.

    I'll let others chime in on the ease of installation.
  2. This heatsink should be fine and it shouldn't be too difficult to install and a number of youtube videos can help you install it.
  3. It's been fine up until now, I actually just cleaned it out an hour ago, hopped on guild wars 2 and it was around 83 degrees, earlier on guild wars 2 it was at 101 degrees (prior to cleaning).

    I cleaned the dust out with a can of compressed air and a napkin, but apparently the latches on the heat sink weren't on all the way (so i latched them back on) not sure if that affects it with the whole thermal paste thing.

    These are really bad temperatures for this CPU. It is dangerous to operate your PC with a CPU running that hot. You can cause permanent damage if you don't stop immediately! I'm currently using a Cooler Master Hyper TX3 EVO, which is the younger brother of the Hyper 212 EVO. The Hyper TX3 EVO uses a 92mm fan, while the 212 EVO a 120mm fan. The TX3 EVO uses the same push pin mounting system, the same system the stock Intel heatsink uses. You said you want an easy to install heatsink, so the TX3 EVO is the best option for you in my opinion. The 212 EVO uses mounting brackets, which can be a little hard to install. It is currently priced at $19.99 on I would also advise you to use a better thermal paste than the one provided by Cooler Master. The Arctic Silver 5 is a great and cheap choice.
  5. @Jay I've been looking at the hyper 212 evo but it seems difficult to install (not the directions) but it just seems like a hassle having to take my motherboard out of the case and everything off of it just to install it, are there any heat sinks that are similar to the stock intel heatsink that work great?
  6. Thanks greekdude, just saw your reply, i'll check that out, and thanks everyone for the help
  7. Thats why i mainly suggested the TX3, you just have to screw in mounting brackets into the heatsink and then mount the heatsink where the intel one was previously (after cleaning the CPU)...

    A lot of ones that are the similar-same size as the intel one would most likely perform the same as the intel one so i dont really see it as a worth it investment.
  8. I can't seem to find the $19.99 Cooler Master Hyper TX3 EVO on new egg, sorry can you link it please?
  9. Yes. If the heatsink is not making direct connection with the CPU, the thermal paste will not work. Thermal paste is a really thin layer so even a slight gap would cause that binding to not work. Thermal paste also tends to dry really quickly as well making them ineffective when exposed. So one thing I would suggest is to clean off the thermal paste and apply new thermal paste. To clean it is simple -- get a bottle of Isopropyl rubbing alcohol (90%+) and a lint-free cloth (coffee filters will work). Then just rub and clean it off both the heatsink and CPU. After it is squeeky clean, wait a few minutes for it to dry off and apply a small amount of thermal paste no bigger than a grain of rice at the center of the CPU. Then install the heatsink and make sure that it is tightly installed this time.

    An aftermarket CPU Cooler is not a bad idea. The plastic pushdowns that the stock Intel coolers come with is crap and can loosen easily. The aftermarket ones usually are not pushdowns and requires actual screws for a very secure mounting.

  11. Alright, thank you!

    Consider yourself lucky ur cpu is still working after it was running that hot ;)
  13. Eh, you're going a little bit over the top. It's not good, but they generally can run that hot for quite a while without trouble. It's that capacitors nearby that you've got to worry about; silicon doesn't really mind.
  14. The max temp (TJunction temperature) according to Intel for the Intel Core i5-3570K is 105C. While 101C is close, it's not hitting it yet.
