I hear what you guys are saying here about the stock cooler, but my idle temps are 26C and that is with 2 7850 in crossfire. I am not sure what it gets like during gaming though. I know my GPUs get up to about 46C when gaming, but never checked my CPU as of yet. New build. Since my system seems to run cool with stock cooler do you think it would be possible to get some overclocking in? i5 5670K on an Asus Z87-A, 8GB 1600MHz ram, 2 HD7850 with slight overclock, Corsair 750 PSU. Case has 5 140mm fans and one 120mm fan. One fan blows directly onto the crossfire setup.
Reason I ask is I have purchased recommend aftermarket Fan/HS in the past and never had it do all the much better on temps. Maybe 2C and felt like I wasted the money. Any good test to look at that show what people are getting with stock vs aftermarket. P.S...Was using Arctic Silver 5 last time I overclocked. If I do get a good one what should I expect to get up to considering my not so high end Motherboard? Thanks.
1 - stock temperatures mean nothing.
2 - If you bought aftermarket coolers and got no gain, then one or more of the following statements are true; the cooler you bought was junk, the TIM you used was junk, the cooler was not installed properly.
There is an excellent collection of reviews on both air and water based cooling solutions on this site. I recommend that you review them and find the best option that fits in your budget. The only thing I would recommend you stay away from is the "direct heat pipe" type coolers. The way the die is situated on the IB/Haswell chips does not lend itself to this kind of cooling, depending on how it's mounted.
