WHat thermal paste for i7 4790 non k?

[Dimitris_1]

Ok so i have the i7 4790 cpu which came with the pre built pc. I have this pc for 1,5 years and temperatures are higher than the first time i used it. From 35-40 c idle to 55-60 idle. What is the best and cheap thermal paste i can get for this cpu and should i change the stock coller for a beter one?

just change the stock cooler witha budet cryorig h7(35 euros/dollars) comes with good thermal paste, it cools way better than the stock cooler and is morie silent at idle i get 26-28c.

if u only want thermal paste artic mx4

I would get either the Cryorig H7 or the Cooler Master Hyper 212 Evo. Either way, you could use the original thermal paste, but I recommend getting Arctic Silver thermal paste.

Several options. You could just do a thermal paste upgrade - Arctic makes many different kinds and you really can't go wrong. I picked up a small syringe of the the Arctic Silver 5 for a few bucks on eBay and it's lasted quite a while to do many CPU installs.

That being said, the stock cooler for normal usage is usually sufficient and you shouldn't notice a big increase in temps over time unless you OC the CPU (which yours is a non-K - so shouldn't be a problem). What could be happening is your fan/cooler could be getting dusty so I would take the cooler off. Clean it out completely (take the fan off and put the thing through the dishwasher using NO detergents - just hot water - harsh chemicals could be problematic for aluminum).

Then clean off the fan, reassemble using new thermal compound (after cleaning off the CPU lid with alcohol of course) and test your temps.

If that doesn't work, then maybe look into a new cooler. The Coolermaster Hyper T4 is a great, very inexpensive solution assuming you have the clearance as it is a 'big air' cooler.

My case is kinda normal to small size cause it was pre built. will a new cooler take too much space?

That's where you need to check clearance height. You could put the computer on it's side, take the side panel off, take off the old cooler. Then, put a straight edge across the sides and use a tape measure straight down to the top of the CPU. Subtract about 1/4-1/2 inch and that's your clearance height.

After that, any decent cooler should list it's height, so make sure you check before you buy it. If you have a 'normal' sized case, as in it accepts full size cards and has some additional clearance above that - you probably have a case similar to a HP I had. In that particular case, lets do some straight up math and use some logic:

It probably takes a standard size DVD/CD, right? Allowing for about an additional 1/2" on each side, we'll assume that one edge of the DVD is even with the motherboard, then allow for 1/4" up from that for the top of the CPU.

So - you have 5.25 inches - .25 inches + .50 inches - total width of 5.50 inches. Converting to mm = 5.5 * 25.4 = 139.7mm (140mm). That means your max cooler height should be under 140mm.

There are many potential good coolers, the Thermalright AXP-100 is a very low clearance unit, and the Noctua C-14 is also quite good. Both should easily clear your case while providing very good CPU cooling.

Of course, get your actual measurement BEFORE buying anything...
