Looking for a better heatsink

Hi all,

My PC has reached 85-89 c when gaming. I figured I need to upgrade the stock cooler, which I know nothing about which one to buy. Here is my build . What would be the cheapest, yet sizable upgrade? What would be the most expensive, but best upgrade?

Thanks in advanced,

Yes. Sneeze and you'll scratch the window.

When I got my CM 690 II, the side panel was not perfectly flat, it had a very slight concave curve. This dropped any cpu clearance height by a good 3-4mm. This happens, more than ppl admit, so coolers with extremely tight tolerances for clearance could be a slight issue. The windows on that case are acrylic and scratch as easily as a cheap pair of sunglasses, and while quality control at CM is usually pretty decent, it is possible for the welds that seal the heatpiping on the top of the heatsink to be off by 1mm.

On the other hand, there's more than a few cases that state a certain clearance, but in reality they short-changed the measurements due to different side panels. A plain metal panel...
Basically:

1) EVO should be cheaper, but slightly noisier at the same temp

2) H7 is more expensive, but less noisy at same temp

BOTH should be fairly quiet, though my experience has been the EVO fan has an odd whine (more than one to confirm) so I ended up replacing the fan for my sister.

*Either way, make sure to set a custom fan profile as this is mostly about limiting the NOISE. At this point I'm assuming you've had the CPU quite a while so it's UNLIKELY that temperature would be what kills it.

Having said that, I'd aim for about 70degC under load as the max as I think that's what AMD recommended (modern Intel is closer to 80degC).

There's no info, anywhere. Not hardwaresecrets review, overclockers club review, TT website, various YouTube videos, nothing nowhere lists maximum height for the cpu cooler. It's amazing just how pathetic that is in an aftermarket case.

There's no guarantee a hyper212 will fit. Many cases will max out at 157 or 159mm etc and a 161mm tall hyper212 is bunk there.

Best bet is contact TT support and find out exactly how tall a cpu cooler can be, since most 120mm coolers will be @ 145-165mm.

My personal favorite would be the Scythe Fuma Rev.b at 149mm, but it's a little more than the Cryorig H7, but will take anything that Phenom can dish out and give you change back.

I have had this computer for about six years now. I have never set a custom fan profile. The stock fan for my current CPU is very loud - At rest with firefox open, it is reads at 45 c and is quite loud.
 
160mm
160mm
160mm

That is the max, so I might err on the side of caution and get the CRYORIG H7 since it's 145mm and the EVO is 159mm.

(159mm is less than 160mm but not sure if you bang the side of the case if that could cause cooler impact that could cause any issues with the CPU mounting... I suspect it would be just FINE but can't confirm 100%)
 
CPU FAN PROFILE:
As per your above, the motherboard BIOS probably has set a fan profile and since it's loud and HOT there's not much you can do to change things right now, but...

When you get a better cooler I'd install the Gigabyte fan software then adjust that to maybe 40% max RPM in idle/light, then ramp up at roughly 45/50degC until 70degC at higher RPM... can't give specifics without being there but you get the idea.

I found this thread: so perhaps it will be fine? They cost both the same for me ($44.00).

Excuse my ignorance, but there is Gigabyte fan software? I probably should have installed this six years ago. That's embarrassing.

What would be the idle temperatures I should go for? As you mentioned above, the maximum should be 70c, not the current estimated max of 89c.

Ahahaha thanks Geef.

Now, I guess the only question is - which cooling system is better? Cooler Master Hyper 212 EVO or the Cryorig H7? I read that the latter is the "EVO killer". But from what I read, the EVO has an addition heat pipe, and higher fan speed. Does this make it better?

On the other hand, there's more than a few cases that state a certain clearance, but in reality they short-changed the measurements due to different side panels. A plain metal panel having 6mm or more clearance due to interior mounting of the window (4mm acrylic etc) so the measurements are based on the smallest size, not the particular panel. Some windows are indented, so actually have more internal clearance than a plain panel, so a 159mm clearance in reality is closer to 164mm, allowing for plenty of cooler choices.

But it's pot-luck. Somebody on the TT faq said 160mm. The 212 evo is stated as 159mm, the 212 Led is stated at 160mm.

That's a whole lot of finger crossing and hoping everything fits to save a few $. The Cryorig H7 not only is a better cooler, at 145mm tall it fits easily with no worries, no ram clearance issues, one of the best mounting systems in the business (the hyper212 mounting is miserable to get right). The H7 has every advantage possible in an air cooler over the 212 in any version except for 1. It's a few $ more.

The fans on my coolers don't exceed 750rpm. They are capable of 1000rpm. Would sticking a 2000rpm fan on it make it better? Not in the slightest. Just means it's less efficient per rpm.

You could throw 40 heatpipes into a cooler, wouldn't make it better than one with 6, just means there's 40. The heatpipes transfer heat like a candle wick, a more efficient heatpipe doing more that 2x inefficient heatpipes. It's all in the engineering and design, not in the actual looks or build.

Thank you for the response. Can you explain why the H7 is a better at cooling? As I said in an above post, the EVO has better RPM and an additional heatpipe. To me this suggests better performance (notwithstanding the size issues). When googling, everyone says the H7 is better but don't explain the technological details.

I just want to learn hahaha.

I was in edit, answer is above.

If a H7 is at 500rpm to keep your cpu at 40°C, and a hyper212 is at 600rpm to keep your cpu at 40°C, what's better?

It's a difference in designs. The hyper212 uses flat plane fins, basically it has a surface area equal to its dimensions. If the fin was 2x2 the surface area being 8 (both sides). The H7 uses honeycomb fins, basically a bunch of tubes. In that same 2x2 area it'll have 10x roundish tubes, so the total surface area is from the circumference of those tubes, being far greater than the hyper212.

The ability to dissipate heat is based on surface area accessible to replacement. Air blown across the 24 of the H7 is going to displace a lot more heat than blown across the 8 of the hyper212. The 212 tries to make up for this lack by increasing rpm (noise) and consequently the cfm (amount of air) blown across.

It's the difference between a guy taking long, slow strides and a geisha taking a million really, really short ones just to keep pace.

Thank you!!

Last question - What are some targets I should expect for temperatures at idle and stressed? Photonboy provided some insight in customizing the fan profile.
